For years, I have been using Google Cloud Print to print labels in our laboratories on campus (to standardize) using a Google Apps Script custom HtmlService form.
Now that GCP is becoming depreciated, I am in on a search for a solution. I have found a few options but am struggling to get the file to convert to a pdf as would be needed with these other vendors.
Currently, when you submit a text/html blob to the GCP servers in GAS, the backend converts the blob to application/pdf (as evidenced by looking at the job details in the GCP panel on Chrome under 'content type').
That said, because these other cloud print services require pdf printing, I have tried for some time now to have GAS change the file to pdf format before sending to GCP and I always get a strange result. Below, I'll show some of the strategies that I have used and include pictures of one of our simple labels generated with the different functions.
The following is the base code for the ticket and payload that has worked for years with GCP
//BUILD PRINT JOB FOR NARROW TAPES
var ticket = {
version: "1.0",
print: {
color: {
type: "STANDARD_COLOR",
vendor_id: "Color"
},
duplex: {
type: "NO_DUPLEX"
},
copies: {copies: parseFloat(quantity)},
media_size: {
width_microns: 27940,
height_microns:40960
},
page_orientation: {
type: "LANDSCAPE"
},
margins: {
top_microns:0,
bottom_microns:0,
left_microns:0,
right_microns:0
},
page_range: {
interval:
[{start:1,
end:1}]
},
}
};
var payload = {
"printerid" : QL710,
"title" : "Blank Template Label",
"content" : HtmlService.createHtmlOutput(html).getBlob(),
"contentType": 'text/html',
"ticket" : JSON.stringify(ticket)
};
This generates the expected following printout:
When trying to convert to pdf using the following code:
The following is the code used to transform to pdf:
var blob = HtmlService.createTemplate(html).evaluate().getContent();
var newBlob = Utilities.newBlob(html, "text/html", "text.html");
var pdf = newBlob.getAs("application/pdf").setName('tempfile');
var file = DriveApp.getFolderById("FOLDER ID").createFile(pdf);
var payload = {
"printerid" : QL710,
"title" : "Blank Template Label",
"content" : pdf,//HtmlService.createHtmlOutput(html).getBlob(),
"contentType": 'text/html',
"ticket" : JSON.stringify(ticket)
};
an unexpected result occurs:
This comes out the same way for direct coding in the 'content' field with and without .getBlob():
"content" : HtmlService.createHtmlOutput(html).getAs('application/pdf'),
note the createFile line in the code above used to test the pdf. This file is created as expected, of course with the wrong dimensions for label printing (not sure how to convert to pdf with the appropriate margins and page size?): see below
I have now tried to adopt Yuri's ideas; however, the conversion from html to document loses formatting.
var blob = HtmlService.createHtmlOutput(html).getBlob();
var docID = Drive.Files.insert({title: 'temp-label'}, blob, {convert: true}).id
var file = DocumentApp.openById(docID);
file.getBody().setMarginBottom(0).setMarginLeft(0).setMarginRight(0).setMarginTop(0).setPageHeight(79.2).setPageWidth(172.8);
This produces a document looks like this (picture also showing expected output in my hand).
Does anyone have insights into:
How to format the converted pdf to contain appropriate height, width
and margins.
How to convert to pdf in a way that would print correctly.
Here is a minimal code to get a better sense of context https://script.google.com/d/1yP3Jyr_r_FIlt6_aGj_zIf7HnVGEOPBKI0MpjEGHRFAWztGzcWKCJrD0/edit?usp=sharing
I've made the template (80 x 40 mm -- sorry, I don't know your size):
https://docs.google.com/document/d/1vA93FxGXcWLIEZBuQwec0n23cWGddyLoey-h0WR9weY/edit?usp=sharing
And there is the script:
function myFunction() {
// input data
var matName = '<b>testing this to <u>see</u></b> if it <i>actually</i> works <i>e.coli</i>'
var disposeWeek = 'end of semester'
var prepper = 'John Ruppert';
var className = 'Cell and <b>Molecular</b> Biology <u>Fall 2020</u> a few exercises a few exercises a few exercises a few exercises';
var hazards = 'Lots of hazards';
// make a temporary Doc from the template
var copyFile = DriveApp.getFileById('1vA93FxGXcWLIEZBuQwec0n23cWGddyLoey-h0WR9weY').makeCopy();
var doc = DocumentApp.openById(copyFile.getId());
var body = doc.getBody();
// replace placeholders with data
body.replaceText('{matName}', matName);
body.replaceText('{disposeWeek}', disposeWeek);
body.replaceText('{prepper}', prepper);
body.replaceText('{className}', className);
body.replaceText('{hazards}', hazards);
// make Italics, Bold and Underline
handle_tags(['<i>', '</i>'], body);
handle_tags(['<b>', '</b>'], body);
handle_tags(['<u>', '</u>'], body);
// save the temporary Doc
doc.saveAndClose();
// make a PDF
var docblob = doc.getBlob().setName('Label.pdf');
DriveApp.createFile(docblob);
// delete the temporary Doc
copyFile.setTrashed(true);
}
// this function applies formatting to text inside the tags
function handle_tags(tags, body) {
var start_tag = tags[0].toLowerCase();
var end_tag = tags[1].toLowerCase();
var found = body.findText(start_tag);
while (found) {
var elem = found.getElement();
var start = found.getEndOffsetInclusive();
var end = body.findText(end_tag, found).getStartOffset()-1;
switch (start_tag) {
case '<b>': elem.setBold(start, end, true); break;
case '<i>': elem.setItalic(start, end, true); break;
case '<u>': elem.setUnderline(start, end, true); break;
}
found = body.findText(start_tag, found);
}
body.replaceText(start_tag, ''); // remove tags
body.replaceText(end_tag, '');
}
The script just changes the {placeholders} with the data and saves the result as a PDF file (Label.pdf). The PDF looks like this:
There is one thing, I'm not sure if it's possible -- to change a size of the texts dynamically to fit them into the cells, like it's done in your 'autosize.html'. Roughly, you can take a length of the text in the cell and, in case it is bigger than some number, to make the font size a bit smaller. Probably you can use the jquery texfill function from the 'autosize.html' to get an optimal size and apply the size in the document.
I'm not sure if I got you right. Do you need make PDF and save it on Google Drive? You can do in Google Docs.
As example:
Make a new document with your table and text. Something like this
Add this script into your doc:
function myFunction() {
var copyFile = DriveApp.getFileById(ID).makeCopy();
var newFile = DriveApp.createFile(copyFile.getAs('application/pdf'));
newFile.setName('label');
copyFile.setTrashed(true);
}
Every time you run this script it makes the file 'label.pdf' on your Google Drive.
The size of this pdf will be the same as the page size of your Doc. You can make any size of page with add-on: Page Sizer https://webapps.stackexchange.com/questions/129617/how-to-change-the-size-of-paper-in-google-docs-to-custom-size
If you need to change the text in your label before generate pdf or/and you need change the name of generated file, you can do it via script as well.
Here is a variant of the script that changes a font size in one of the cells if the label doesn't fit into one page.
function main() {
// input texts
var text = {};
text.matName = '<b>testing this to <u>see</u></b> if it <i>actually</i> works <i>e.coli</i>';
text.disposeWeek = 'end of semester';
text.prepper = 'John Ruppert';
text.className = 'Cell and <b>Molecular</b> Biology <u>Fall 2020</u> a few exercises a few exercises a few exercises a few exercises';
text.hazards = 'Lots of hazards';
// initial max font size for the 'matName'
var size = 10;
var doc_blob = set_text(text, size);
// if we got more than 1 page, reduce the font size and repeat
while ((size > 4) && (getNumPages(doc_blob) > 1)) {
size = size-0.5;
doc_blob = set_text(text, size);
}
// save pdf
DriveApp.createFile(doc_blob);
}
// this function takes texts and a size and put the texts into fields
function set_text(text, size) {
// make a copy
var copyFile = DriveApp.getFileById('1vA93FxGXcWLIEZBuQwec0n23cWGddyLoey-h0WR9weY').makeCopy();
var doc = DocumentApp.openById(copyFile.getId());
var body = doc.getBody();
// replace placeholders with data
body.replaceText('{matName}', text.matName);
body.replaceText('{disposeWeek}', text.disposeWeek);
body.replaceText('{prepper}', text.prepper);
body.replaceText('{className}', text.className);
body.replaceText('{hazards}', text.hazards);
// set font size for 'matName'
body.findText(text.matName).getElement().asText().setFontSize(size);
// make Italics, Bold and Underline
handle_tags(['<i>', '</i>'], body);
handle_tags(['<b>', '</b>'], body);
handle_tags(['<u>', '</u>'], body);
// save the doc
doc.saveAndClose();
// delete the copy
copyFile.setTrashed(true);
// return blob
return docblob = doc.getBlob().setName('Label.pdf');
}
// this function formats the text beween html tags
function handle_tags(tags, body) {
var start_tag = tags[0].toLowerCase();
var end_tag = tags[1].toLowerCase();
var found = body.findText(start_tag);
while (found) {
var elem = found.getElement();
var start = found.getEndOffsetInclusive();
var end = body.findText(end_tag, found).getStartOffset()-1;
switch (start_tag) {
case '<b>': elem.setBold(start, end, true); break;
case '<i>': elem.setItalic(start, end, true); break;
case '<u>': elem.setUnderline(start, end, true); break;
}
found = body.findText(start_tag, found);
}
body.replaceText(start_tag, '');
body.replaceText(end_tag, '');
}
// this funcion takes saved doc and returns the number of its pages
function getNumPages(doc) {
var blob = doc.getAs('application/pdf');
var data = blob.getDataAsString();
var pages = parseInt(data.match(/ \/N (\d+) /)[1], 10);
Logger.log("pages = " + pages);
return pages;
}
It looks rather awful and hopeless. It turned out that Google Docs has no page number counter. You need to convert your document into a PDF and to count pages of the PDF file. Gross!
Next problem, even if you managed somehow to count the pages, you have no clue which of the cells was overflowed. This script takes just one cell, changes its font size, counts pages, changes the font size again, etc. But it doesn't granted a success, because there can be another cell with long text inside. You can reduce font size of all the texts, but it doesn't look like a great idea as well.
I'm new to Stackoverflow and this will be my first question. My HTML5 player works fine on Internet Explorer but doesn't work on google chrome. I'm using a PlayReady stream which is encrypted with CENC. How can I let this work on chrome? I don't have access to the servers, they're run by third parties.
Thanks
Technically it is possible to support Widevine while you're stream is PlayReady. This is possible since you use CENC. Since you don't have access to the servers like you mentioned you can use a technique called PSSH Forging. It basically replaces the pieces to make chrome think it's Widevine, since it's CENC the CDM will decrypt the video and the stream will play.
For the sake of ease i'm going to assume you use DASH.
We have here a PSSH Box:
const widevinePSSH = '0000005c7073736800000000edef8ba979d64acea3c827dcd51d21ed0000003c080112101c773709e5ab359cbed9512bc27755fa1a087573702d63656e63221848486333436557724e5a792b32564572776e64562b673d3d2a003200';
You need to replace 1c773709e5ab359cbed9512bc27755fa with your KID.
And then at the part where you insert you'r segment in the SourceBuffer (before appendSegment) you can do the following:
let segment = args[0];
segment = new Uint8Array(segment);
const newPssh = widevinePSSH.replace('1c773709e5ab359cbed9512bc27755fa', psshKid);
const subArray = new Uint8Array(DRMUtils.stringToArrayBuffer('70737368'));
let index = 0;
const found = subArray.every((item) => {
const masterIndex = segment.indexOf(item, index);
if (~masterIndex) {
index = masterIndex;
return true;
}
});
if (found) {
return originalSourceBufferAppendBuffer.apply(this, [].slice.call(args));
}
segment = DRMUtils.uInt8ArrayToHex(segment);
// Inject the forged signal
// 70737368 = pssh
segment = segment.substr(0, segment.lastIndexOf('70737368') - 8) + newPssh + segment.substr(segment.lastIndexOf('70737368') - 8);
// Fix the MOOV atom length
// 6d6f6f76 = moov
const header = segment.substr(0, segment.indexOf('6d6f6f76') - 8);
const payload = segment.substr(segment.indexOf('6d6f6f76') - 8);
const newLength = Math.floor(payload.length / 2);
segment = header + DRMUtils.intToHex(newLength, 8) + payload.substr(8);
segment = decode(segment).b;
Sadly i can only share bits and pieces but this is roughly what you should do to get it working.
Please be kind, I'm new to Fiddler

At first I was going to go with Tampermonkey userscripts,Because I did not know about Fiddler
==================================================================================
Now,lets focus on Fiddler
Before Request:
I want Fiddler to add text at the end of Google Query string.
Someone suggested me to use
static function OnBeforeRequest(oSession: Session) {
if (oSession.uriContains("targetString")) {
var sText = "Enter a string to append to a URL";
oSession.fullUrl = oSession.fullUrl + sText;
}
}
Before Response:
This is where my problem lies
I totally love the HTML response,Now I just want to scrape/hide the word in the search box without changing the search results.How can it be done? Any Ideas?

Can you guys please take the above information and fix the problem for me
Thank you
Basing on goal definition above, I believe you can achieve better results with your own free Google custom search engine service. In particular, because you have control over GCSE fine-tuning results, returned by regular Google search.

activeDocument.fitArtboardToSelectedArt()
When calling this command, AI crashes on AI 5.1/6 32bit and 64bit versions. I can use the command from the menu. Has anyone encountered this? does anyone know of a work around?
The full code.
function exportFileToJPEG (dest) {
if ( app.documents.length > 0 ) {
activeDocument.selectObjectsOnActiveArtboard()
activeDocument.fitArtboardToSelectedArt()//crashes here
activeDocument.rearrangeArtboards()
var exportOptions = new ExportOptionsJPEG();
var type = ExportType.JPEG;
var fileSpec = new File(dest);
exportOptions.antiAliasing = true;
exportOptions.qualitySetting = 70;
app.activeDocument.exportFile( fileSpec, type, exportOptions );
}
}
var file_name = 'some eps file.eps'
var eps_file = File(file_name)
var fileRef = eps_file;
if (fileRef != null) {
var optRef = new OpenOptions();
optRef.updateLegacyText = true;
var docRef = open(fileRef, DocumentColorSpace.RGB, optRef);
}
exportFileToJPEG ("output_file.jpg")
I can reproduce the bug with AI CS5.
It seems that fitArtboardToSelectedArt() takes the index of an artboard as an optional parameter. When the parameter is set, Illustrator doesn't crash. (probably a bug in the code handling the situation of no parameter passed)
As a workaround you could use:
activeDocument.fitArtboardToSelectedArt(
activeDocument.artboards.getActiveArtboardIndex()
);
to pass the index of the active artboard with to the function. Hope this works for you too.
Also it's good practice to never omit the semicolon at the end of a statement.
I have a problem running the NativeProcess if I put spaces in the arguments
if (Capabilities.os.toLowerCase().indexOf("win") > -1)
{
fPath = "C:\\Windows\\System32\\cmd.exe";
args.push("/c");
args.push(scriptDir.resolvePath("helloworld.bat").nativePath);
}
file = new File(fPath);
var nativeProcessStartupInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo();
nativeProcessStartupInfo.executable = file;
args.push("blah");
nativeProcessStartupInfo.arguments = args;
process = new NativeProcess();
process.start(nativeProcessStartupInfo);
in the above code, if I use
args.push("blah") everything works fine
if I use
args.push("blah blah") the program breaks as if the file wasn't found.
Seems like I'm not the only one:
http://tech.groups.yahoo.com/group/flexcoders/message/159521
As one of the users their pointed out, it really seems like an awful limitation by a cutting edge SDK of 21st century. Even Alex Harui didn't have the answer there and he's known to workaround every Adobe bug:)
Any ideas?
I am using AIR 2.6 SDK in JavaScript like this, and it is working fine even for spaces.
please check your code with this one.
var file = air.File.applicationDirectory;
file = file.resolvePath("apps");
if (air.Capabilities.os.toLowerCase().indexOf("win") > -1)
{
file = file.resolvePath(appFile);
}
var nativeProcessStartupInfo = new air.NativeProcessStartupInfo();
nativeProcessStartupInfo.executable = file;
var args =new air.Vector["<String>"]();
for(i=0; i<arguments.length; i++)
args.push(arguments[i]);
nativeProcessStartupInfo.arguments = args;
process = new air.NativeProcess();
process.addEventListener(air.ProgressEvent.STANDARD_OUTPUT_DATA, onOutputData);
process.addEventListener(air.ProgressEvent.STANDARD_INPUT_PROGRESS, inputProgressListener);
process.start(nativeProcessStartupInfo);
To expand on this: The reason that this works (see post above):
var args =new air.Vector["<String>"]();
for(i=0; i<arguments.length; i++)
args.push(arguments[i]);
nativeProcessStartupInfo.arguments = args;
is that air expects that the arguments being passed to the nativeProcess are delimited by spaces. It chokes if you pass "C:\folder with spaces\myfile.doc" (and BTW for AIR a file path for windows needs to be "C:\\folder with spaces\\myfile.doc") you would need to do this:
args.push("C:\\folder");
args.push("with");
args.push("spaces\\myfile.doc");
Hence, something like this works:
var processArgs = new air.Vector["<String>"]();
var path = "C:\\folder with spaces\\myfile.doc"
var args = path.split(" ")
for (var i=0; i<args.length; i++) {
processArgs.push(args[i]);
};
UPDATE - SOLUTION
The string generated by the File object by either nativePath or resolvePath uses "\" for the path. Replace "\" with "/" and it works.
I'm having the same problem trying to call 7za.exe using NativeProcess. If you try to access various windows directories the whole thing fails horribly. Even trying to run command.exe and calling a batch file fails because you still have to try to pass a path with spaces through "arguments" on the NativeProcessStartupInfo object.
I've spent the better part of a day trying to get this to work and it will not work. Whatever happens to spaces in "arguments" totally destroys the path.
Example 7za.exe from command line:
7za.exe a MyZip.7z "D:\docs\My Games\Some Game Title\Maps\The Map.map"
This works fine. Now try that with Native Process in AIR. The AIR arguments sanitizer is FUBAR.
I have tried countless ways to put in arguments and it just fails. Interesting I can get it to spit out a zip file but with no content in the zip. I figure this is due to the first argument set finally working but then failing for the path argument.
For example:
processArgs[0] = 'a';
processArgs[1] = 'D:\apps\flash builder 4.5\project1\bin-debug\MyZip.7z';
processArgs[2] = 'D:\docs\My Games\Some Game Title\Maps\The Map.map';
For some reason this spits out a zip file named: bin-debugMyZip.7z But the zip is empty.
Whatever AIR is doing it is fraking up path strings. I've tried adding quotes around those paths in various ways. Nothing works.
I thought I could fall back on calling a batch file from this example:
http://technodesk.wordpress.com/2010/04/15/air-2-0-native-process-batch-file/
But it fails as well because it still requires the path to be passed through arguments.
Anyone have any luck calling 7z or dealing with full paths in the NativeProcess? All these little happy tutorials don't deal with real windows folder structure.
Solution that works for me - set path_with_space as "nativeProcessStartupInfo.workingDirectory" property. See example below:
public function openPdf(pathToPdf:String):void
}
var nativeProcessStartupInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo();
var file:File = File.applicationDirectory.resolvePath("C:\\Windows\\System32\\cmd.exe");
nativeProcessStartupInfo.executable = file;
if (Capabilities.os.toLowerCase().indexOf("win") > -1)
{
nativeProcessStartupInfo.workingDirectory = File.applicationDirectory.resolvePath(pathToPdf).parent;
var processArgs:Vector.<String> = new Vector.<String>();
processArgs[0] = "/k";
processArgs[1] = "start";
processArgs[2] = "test.pdf";
nativeProcessStartupInfo.arguments = processArgs;
process = new NativeProcess();
process.start(nativeProcessStartupInfo);
process.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onOutputData);
}
args.push( '"blah blah"' );
Command line after all supports spaces if they are nested whithin "".
So if lets say you have a file argument :
'test/folder with space/blah'
Convert it to the following
'test/"folder with space"/blah'
Optionally use a filter:
I once had a problem like this in AIR, i just simply filter the text before i push it into the array. My refrence use CASA lib though
import org.casalib.util.ArrayUtil;
http://casalib.org/
/**
* Filters a string input for 'safe handling', and returns it
**/
public function stringFilter(inString:String, addPermitArr:Array = null, permitedArr:Array = null):String {
var sourceArr:Array = inString.split(''); //Splits the string input up
var outArr:Array = new Array();
if(permitedArr == null) {
permitedArr = ("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890" as String).split('');
}
if( addPermitArr != null ) {
permitedArr = permitedArr.concat( addPermitArr );
}
for(var i:int = 0; i < sourceArr.length; i++) {
if( ArrayUtil.contains( permitedArr, sourceArr[i] ) != 0 ) { //it is allowed
outArr.push( sourceArr[i] );
}
}
return (outArr.join('') as String);
}
And just filter it via
args.push( stringFilter( 'blah blah', new Array('.') ) );
Besides, it is really bad practice to use spaces in file names / arguments, use '_' instead. This seems to be originating from linux though. (The question of spaces in file names)
This works for me on Windws7:
var Xargs:Array = String("/C#echo#a trully hacky way to do this :)#>#C:\\Users\\Benjo\\AppData\\Roaming\\com.eblagajna.eBlagajna.POS\\Local Store\\a.a").split("#");
var args:Vector.<String> = new Vector.<String>();
for (var i:int=0; i<Xargs.length; i++) {
trace("Pushing: "+Xargs[i]);
args.push(Xargs[i]);
};
NPI.arguments = args;
If your application path or parameter contains spaces, make sure to wrap it in quotes. For example path of the application has spaces C:\Program Files (x86)\Camera\Camera.exe use quotes like:
"C:\Program Files (x86)\Camera\Camera.exe"
