Hi folks,

I'm trying to setup under my newly installed CentOS 7 two printers connected through print servers. For simplicity I will just talk only about 1 of these 2 printers as the issue and symptoms are exactly the same for both of the printers.

My setup contains HP LJ1100 connected to print server Edimax PS-1206P. Everything worked fine on old Mandriva or CentOS 6.5 until I installed CentOS 7 with cups 1.6. When I setup the printer directly through standard GUI and use socket: or ipp: or lpd: the printer prints always only few lines on the first page and then it prints empty sheets of paper. I tried to debug it and therefore setup exactly the same printer under CentOS 6.5 with cups 1.4 in the same way where printing worked fine out of the box without issue. So it's not the print server to be blamed (I tested it also from Win7). It leads me to cups 1.6 issue or backend.

My question is if anybody of you encountered such an issue with network printers and cups 1.6. Did anybody of you have such problems and did anybody resolve that?

N.B. For many years I was using paid Turboprint and wanted to use it now as well. So I purchased the latest version and setup printers as they were setup on older OS and the behaviour is the same as described above with native printer setup. Only few lines are printed and then many blank sheets.

Thanks for your advice,
Jan

I'm not familiar with CentoOS, but perhaps version 6.5 was using CUPS 1.4.x?, and the printing work-flow has since changed to using pdf-based printing, which for the most-part should be transparent to the user, but I know some drivers have had issues as a result. I'm wondering if you've been impacted by this?

Does this happen with particular documents (eg .pdf, doc,...)?
Is it application-related printing issue (ie the issue presents itself when printing via certain applications)?
Is paper size set correctly?

Which driver is in use? I note that hplip driver is recommended for this printer

Hi Ferrari,

the CentOS 6.5 is using cups version 1.4.x, that's correct. The cups 1.6 uses PDF while 1.4 used PS. This issue is not related to application from I'm printing or the format of the file, I believe. I tried simple printing via lpd from cmd line, from OpenOffice, from Emacs, from Evince etc. I tried PDFs, ODTs, TXTs etc. The behaviour is the same. So I think it's not related to file type nor user application.

The driver used is hplip (if the printer is set directly in the system) or Turboprint GS (if set in the Turboprint). I believe it's something to do with the backend of the cups.

To give you more information, I tried small test. I set the printer on my server running CentOS 6.5 as shared (via cups 1.4.x). Then I set new printer on my CentOS 7 and provided ipp: URI to the cups server on the CentOS 6.5. I also set a new printer in Turboprint again as ipp: on cups server. The result is that I was able to print on the printer again through both added system printer or Turboprint printer. In this scenario that means I'm using driver on my CentOS 7 and then transferring my print job to cups 1.4.x server on CentOS 6.5 which transfers it to JetDirect print server. It's not very efficient workaround for the moment but it works. I think it's CentOS 7 cups 1.6 backend related problem and I will rise a bug tracker on CentOS site.

Does anybody have any idea what could be wrong?

Thanks,
Jan

Yes, I think a bug report is your best bet here.
