We use Acrobat 10 standard in a Windows 7 64-bit enterprise environment. The printers involved are Xerox copiers using the latest PostScript 3 drivers.
We are currently having an issue where we print a document and on the paper copy, some of the characters are replaced with a square character. The problem occurs when printing a PDF with Acrobat 10. The problem does not occur when printing with Acrobat 9 but we did a company wide upgrade to 10 so 9 is no longer available.
I read elsewhere that one of the solutions was to use Pre-flight to check for issues prior to printing. However, the standard version of Acrobat does not have that feature. I also used the print as an image option, which works, however the quality is severely degraded, even at 600 dpi. I have also tried printing to the Xerox copiers with the PCL drivers and that prints ok but the margins and character sizes are distorted so we need to use PostScipt.
While this problem applies to many of our documents, the most commons ones that have the issue are PDFs that have been edited to include additional pages from another PDF so they are combined into one larger PDF.
The current workaround I have is to save the PDF file as a PS file, then double-click the PS file to have the distiller regenerate the PDF. Afterwards it prints just fine. However, since we have thousands of PDF documents with this potential problem, it is quite counter-productive to have to do this workaround to each document.
Per Adobe support, I have tried uninstalling and reinstalling Acrobat 10, I have also tried printing with Adobe Reader 11 and same problem occurs. However, it will print fine with Adobe Reader 9. Updating to the latest version of Acrobat 10 (10.1.5) has had no improvement.
I have included a sample attached of what it looks like on paper. Is there a setting in Acrobat 10 standard that I could possibly try that may work for us?
