PDFBox Convert PDF to lower version - pdfbox

I have a program that outputs a PDF file using PDFBox (It merges a bunch of PDFs using PDFMergerUtility).
I need to use Acrobat 5 to read that PDF, but in some pages i get Error proccesing page. A drawing error ocurred.
I cant update my acrobat so, there is a way to downgrade the PDF using PDFbox?

Print to pdf that is searchable and selectable from existing pdf that is selectable and searchable

I am trying to print a section of an existing pdf to a new pdf. The original is searchable and selectable but the new pdf cannot do either. I am using "adobe acrobat reader DC" and print via "Microsoft Print to PDF". Unsure if there is any other relevant information.
After searching for a period of time I could not find an answer that allows for direct PDF to PDF print.
I did find a workaround however.
I downloaded a free software called PrimoPDF. Once installed, PrimoPDF becomes a printer option within Adobe acrobat reader. I then selected my desired pages and printed to PrimoPDf instead of Microsoft Print to PDF. This Generated a .ps file. I then imported the .ps file into PrimoPDF application and was able to generate a .pdf from that. The newly generated pdf was searchable and selectable and exactly what I needed.
Hopefully someone else finds this useful in the future.
Generally refrying (printing to PostScript then converting back to PDF) is a bad idea. The reason that Microsoft Print to PDF created a file that wasn't searchable is because when Adobe Reader detects that the printer it is targeting isn't capable of rendering the PDF correctly because of any number of reasons, like it doesn't have the right fonts for example, it will render the PDF itself and send an image to the printer. A simpler PDF probably would have worked just fine.
You are much better off getting a tool that will simply allow you to extract the pages you need to a new file rather than printing.

SyncFusion, Bad PDF Format, Inverted Color on Inputs

So the state publishes PDF files for us to download. However these files only look right in Adobe Acrobat. When I try to open them in PDFSharp or SyncFusion it fails with the error that there are no pages. When I have PDFSharp or SyncFusion create a new file from the pages in the PDF the result is the following;
However if I save this document as an archive-able PDF/A in Adobe Acrobat Pro, the file straightens out and both PDFSharp and SyncFusion have no problems printing and viewing the resulting PDF file. I can't get SyncFusion to re-save the document as a PDF/A and have it fix like with Adobe.
What could cause this issue?
Edit: The PDF file says it was created by an Elixir program which converts open document formats to PDF. Possibly Librex.

itextsharp joined pdf size too large

I have an asp.net (c#) web application.
I joined together some pdf files on serverside with itextsharp.
The result pdf is too large (>1M) to be downloaded in our environment.
I checked fonts list in Adobe Reader and Verdana font embedded 10 times. It could be a problem. I don't know why? I use iTextSharp PDFCopy for merging.
If I capture the file by fiddler and than print it out by bullzip pdf printer the size become the half (500KB)!!!
I can't figure out what bullzip pdf printer does to reduce the size???
All the joined pdfs are mosty text only a couple of small images.
Interesting when I try to copy/paste text from the original pdf I can, but I can't from the bullzip printed version (i get only rectangles when paste). That is no problem by the way because I don't need to edit or search by text, I only need to print it from the browser.
I need some .net library to do the same with the pdf before I send it to the browser.
Can anyone help me?

BIRT pdf report print issue in pdf complete

I have a pdf file which got exported from BIRT report. I tried opening that pdf file in adobe acrobat and tried printing it. It got printed properly.
But when I try to open the same pdf file using PDF complete and print it nothing gets printed. But the pdf file is getting opened in PDF complete properly.
Is birt pdf report not compatible with printing using pdf complete or so?
BIRT is compatible with creating printable PDF.
There is insufficeint information here about discover the users specific issue.
What version of BIRT is being used?
How is the PDF being 'exported' (as opposed to open as)?
How is the PDF being saved?

What is the minimum Adobe Reader version needed for PDFs generated by ColdFusion 8?

I'm using ColdFusion 8 and creating PDFs dynamically with CFDOCUMENT. What is the minimum version of Adobe Reader needed to view these PDFs?
If you open up the Document Properties of the generated PDF, you'll see:
PDF Producer: iText 2.1.0 (by
lowagie.com)
PDF Version: 1.4 (Acrobat 5.x)
I generate the PDF using CF9.0.1, but I guess it's the same for CF8.
Or open the PDF in a text editor and look at the first line. It will say something like
%PDF-1.4
That is the version number (the second number is always 1 less than the version of Acrobat needed).
Don't save the file as you could break it!
