Description Richard Ulmer

2017-04-10 14:17:17 CEST

When I execute "lpr -PPDFDrucker -U aaltmayer manual-4.1.pdf" on a DC (where aaltmayer is a student) there will appear an empty document in the "Moderate Printers" module.

When executing the same command with a postscript document (e.g. "lpr -PPDFDrucker -U aaltmayer mozilla.ps") there will appear a broken (not displayable) pdf in the "Moderate Printers" module.

I was unable to reproduce this error. On my UCS@school 4.2 slave, the UCS release notes .ps file has been successfully been "printed" on the PDF printer and shown in "printer moderation".

I was able to reproduce this bug on an UCS@school 4.3.
I executed the command as a student user with a pdf and a ps file.
The ps file was "printed" as expected (not broken) but the pdf was blank.

This issue has been filed against UCS@school 4.3.

UCS@school 4.3 is out of maintenance and many UCS@school components have changed in later releases. Thus, this issue is now being closed.

If this issue still occurs in newer UCS@school versions, please reopen it and update the UCS@school version. In this case please provide detailed information on how this issue is affecting you.

UCS: 5.0-0 errata127

I could reproduce the problem with lpr, but also when printing from my windows vm.
