Ready for a fun one, experts? Most users on our network have .pdf factory to create .pdf files. 3 users have full blown versions of Acrobat, mostly used to combine multiple files (.pdfs or Microsoft Office documents) into one .pdf One of our Acrobat users has noticed when combining multiple documents into a single .pdf that random letters are dropped. This has happened with Arial and recently Garamond fonts.
There are no dropped letters when viewing the .pdf on the screen, but the print out has letters missing. The same issue occurs on multiple networked printers. The printers will handle other .pdf documents without dropping letters.
I have replaced print drivers (universal, PS and PCL) and sampled the same document on all three machines with Acrobat. The issue remains consistently inconsistent - dropping different letters (regular, bold or italic), occurring randomly on the same document, now with 2 different fonts.
Any ideas on how to eliminate possible causes and narrow down the root issue?
