Not a systemic issue - some users are unable to save Infomaker reports as PDF files. They receive an error pop-up:
"Unable to save report data to <save_location>. Disk may be full or write-protected or PDF capability is not installed"
All client machines are the same build so I don't think there is missing functionality if some users can save to PDF and some can't.
I'll submit a ticket as well just in case it is a real technical issue
Another option to try would be:
1) On the computer where the printer driver will not install properly, install another Postscript Printer--such as AppleLaserWriter II NTX v51.8.
2) Rename the newly installed Apple printer to "Sybase Datawindow PS" on the computer.
3) Then see if you can save a report as a PDF on the Report Server machine.
Sometimes this solves the issue, even if downloading the driver from http://www.adobe.com/support/downloads/thankyou.jsp?ftpID=1500&fileID=1438 does not.
