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 have to put my list data in a table in a pdf file. My data has some Arabic words. When my pdf is generated, the Arabic words don't appear. I searched and found that I need itext7.pdfcalligraph so I installed it in my app. I found this code too https://itextpdf.com/en/blog/technical-notes/displaying-text-different-languages-single-pdf-document and tried to do something similar to allow Arabic words in my table but I couldn't figure it out.
This is a trial code before I apply it to my real list:
var path2 = global::Android.OS.Environment.ExternalStorageDirectory.AbsolutePath;
filePath = System.IO.Path.Combine(path2.ToString(), "myfile2.pdf");
stream = new FileStream(filePath, FileMode.Create);
PdfWriter writer = new PdfWriter(stream);
PdfDocument pdf2 = new iText.Kernel.Pdf.PdfDocument(writer);
Document document = new Document(pdf2, PageSize.A4);
FontSet set = new FontSet();
set.AddFont("ARIAL.TTF");
document.SetFontProvider(new FontProvider(set));
document.SetProperty(Property.FONT, "Arial");
string[] sources = new string[] { "يوم","شهر 2020" };
iText.Layout.Element.Table table = new iText.Layout.Element.Table(2, false);
foreach (string source in sources)
{
Paragraph paragraph = new Paragraph();
Bidi bidi = new Bidi(source, Bidi.DirectionDefaultLeftToRight);
if (bidi.BaseLevel != 0)
{
paragraph.SetTextAlignment(iText.Layout.Properties.TextAlignment.RIGHT);
}
paragraph.Add(source);
table.AddCell(new Cell(1, 1).SetTextAlignment(iText.Layout.Properties.TextAlignment.CENTER).Add(paragraph));
}
document.Add(table);
document.Close();
I updated my code and added the arial.ttf to my assets folder . i'm getting the following exception:
System.InvalidOperationException: 'FontProvider and FontSet are empty. Cannot resolve font family name (see ElementPropertyContainer#setFontFamily) without initialized FontProvider (see RootElement#setFontProvider).'
and I still can't figure it out. any ideas?
thanks in advance

I have a similar situation for Turkish characters, and I've followed these
steps :
Create a folder under projects root folder which is : /wwwroot/Fonts
Add OpenSans-Regular.ttf under the Fonts folder
Path for font is => ../wwwroot/Fonts/OpenSans-Regular.ttf
Create font like below :
public static PdfFont CreateOpenSansRegularFont()
{
var path = "{Your absolute path for FONT}";
return PdfFontFactory.CreateFont(path, PdfEncodings.IDENTITY_H, true);
}
and use it like :
paragraph.Add(source)
.SetFont(FontFactory.CreateOpenSansRegularFont()); //set font in here
table.AddCell(new Cell(1, 1)
.SetTextAlignment(iText.Layout.Properties.TextAlignment.CENTER)
.Add(paragraph));
This is how I used font factory for Turkish characters ex: "ü,i,ç,ş,ö"
For Xamarin-Android, you could try
string documentsPath = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
var path = Path.Combine(documentsPath, "Fonts/Arial.ttf");
Look i fixed it in java,this may help you:
String font = "your Arabic font";
//the magic is in the next 4 lines:
PdfFontFactory.register(font);
FontProgram fontProgram = FontProgramFactory.createFont(font, true);
PdfFont f = PdfFontFactory.createFont(fontProgram, PdfEncodings.IDENTITY_H);
LanguageProcessor languageProcessor = new ArabicLigaturizer();
//and look here how i used setBaseDirection and don't use TextAlignment ,it will work without it
com.itextpdf.kernel.pdf.PdfDocument tempPdfDoc = new com.itextpdf.kernel.pdf.PdfDocument(new PdfReader(pdfFile.getPath()), TempWriter);
com.itextpdf.layout.Document TempDoc = new com.itextpdf.layout.Document(tempPdfDoc);
com.itextpdf.layout.element.Paragraph paragraph0 = new com.itextpdf.layout.element.Paragraph(languageProcessor.process("الاستماره الالكترونية--الاستماره الالكترونية--الاستماره الالكترونية--الاستماره الالكترونية"))
.setFont(f).setBaseDirection(BaseDirection.RIGHT_TO_LEFT)
.setFontSize(15);
As the title says i get "Value of type EmbedBuilder cannot be converted to Embed" error.
This is the code i'm trying right now :
If msg.Equals("gDurum") Then
Dim eb As New EmbedBuilder With {
.Title = "Sunucu Bilgisi",
.Color = New Color(255, 0, 0),
.ImageUrl = "https://cache.gametracker.com/server_info/185.198.73.27:27015/b_560_95_1.png",
.Description = "Deneme"
}
eb.Build()
Await message.Channel.SendMessageAsync("", False, eb)
OK. I found the solution. I was trying to pass the EmbedBuilder instead of Embed.
Here's my new code :
If msg.Equals("gDurum") Then
Dim eb As New EmbedBuilder With {
.Title = "Sunucu Bilgisi",
.Color = New Color(255, 0, 0),
.ImageUrl = "https://cache.gametracker.com/server_info/185.198.73.27:27015/b_560_95_1.png",
.Description = "Deneme"
}
Await message.Channel.SendMessageAsync("", False, eb.Build())
For those who are looking at the official code example might encounter type mismatch while compiling.
Make sure to build Discord.Embed into a Rich Embed which is ready to be sent.
Corrected & working code example for this:
[Command("embed")]
public async Task SendRichEmbedAsync()
{
var embed = new EmbedBuilder
{
// Embed property can be set within object initializer
Title = "Hello world!"
Description = "I am a description set by initializer."
};
// Or with methods
embed.AddField("Field title",
"Field value. I also support [hyperlink markdown](https://example.com)!")
.WithAuthor(Context.Client.CurrentUser)
.WithFooter(footer => footer.Text = "I am a footer.")
.WithColor(Color.Blue)
.WithTitle("I overwrote \"Hello world!\"")
.WithDescription("I am a description.")
.WithUrl("https://example.com")
.WithCurrentTimestamp();
await ReplyAsync(embed: embed.Build());
}
I'd folow the example From I200 pdf for a stock item, but I dont' know how to download the file from an Sales Order. Does anybody has a clue?
IN202500Content stockItemSchema = context.IN202500GetSchema();
var commands = new Command[]
{
new Value
{
Value = "AAMACHINE1",
LinkedCommand = stockItemSchema.StockItemSummary.InventoryID
},
new Value
{
FieldName = "T2MCRO.jpg",
LinkedCommand =
stockItemSchema.StockItemSummary.ServiceCommands.Attachment
}
};
var stockItemAttachment =
context.IN202500Export(commands, null, 1, false, true);
You were almost there, in the "stockItemAttachment" variable you should have the content of the file "T2MCRO.jpg" in byte format.
The only thing you have left to do is to write it to your file system.
You can use the following command :
File.WriteAllBytes(Path, Convert.FromBase64String(stockItemAttachment[0][0]));
I am using an sdk from pdftron,which reads a single page at a time. My code would be:
PDFDoc doc = new PDFDoc(input_path);
doc.InitSecurityHandler();
PageIterator itr = doc.GetPage(1);
for (line = txt.GetFirstLine(); line.IsValid(); line = line.GetNextLine()){
for (word = line.GetFirstWord(); word.IsValid(); word = word.GetNextWord()){
Console.WriteLine(word.GetString());
}
}
I want to read each and every page, I had posted my same problem in PDFTRON forums.But couldn't get the solution for this.
Is it possible to read each and every pages?
Yes,you can read each and every pages of pdf at a time.You need to do just s slight change initializing page iterator.
I have modified the code,and it works fine.
PDFDoc doc = new PDFDoc(input_path);
doc.InitSecurityHandler();
PageIterator itr = doc.GetPageIterator();
for (; itr.HasNext(); itr.Next()) // Read every page
{
for (line = txt.GetFirstLine(); line.IsValid(); line = line.GetNextLine())
{
for (word = line.GetFirstWord(); word.IsValid(); word = word.GetNextWord())
{
Console.WriteLine(word.GetString());
}
}
}
Hope this will help you.
