Hello,

I have a Brother DCP-115C and with the MFC210 driver from Brother I have been able to print all types of files from all applications under openSUSE. But now with openSUSE 11.1 (using the same Brother driver I have used since I think openSUSE 9.3 or earlier), Postscript files are not graphically interpreted: the printer outputs the compiled Postscript code. If I convert the Postscript file to PDF, it prints out fine. ... ... a suggestion how to try to diagnose it?
Have a look at http://en.opensuse.org/SDB:Using_Your_Own_Filters_to_Print_with_CUPS to get an idea how the CUPS filtering works and for the basics see http://en.opensuse.org/SDB:CUPS_in_a_Nutshell
Then inspect /var/log/cups/error_log which filters are run for your PostScript files, see the section "If problems are encountered:" in http://en.opensuse.org/SDB:CUPS_in_a_Nutshell
Look for "Request file type" and "File of type" and "Started filter" lines in the error_log and possible subsequent (error)-messages.
Many thanks for the pointers and suggestions. Surprisingly, I cannot now reproduce the PostScript problem I reported, that is, I just now printed out the same and other PostScript files fine. I don't know what this means -- if the problem yesterday was some momentary inexplicable glitch, or something else -- but I guess I should just be happy it's working (as long as it keeps working!). For the record, I'll respond to a couple of points concerning the problem I reported. Here are the entries in error_log during one of the failed print jobs: I [27/Jan/2009:15:54:11 +0100] [Job ???] Request file type is application/postscript. I [27/Jan/2009:15:54:11 +0100] [Job 148] Adding start banner page "none". I [27/Jan/2009:15:54:11 +0100] [Job 148] Adding end banner page "none". I [27/Jan/2009:15:54:11 +0100] [Job 148] File of type application/postscript queued by "steve". I [27/Jan/2009:15:54:11 +0100] [Job 148] Queued on "Brother_DCP-115C_USB_1" by "steve".

I don't see anything suspicious here (I canceled the job when I saw it printing the PostScript code).
Because PostScript files are graphically interpreted on my openSUSE 11.1 workstation I assume that something goes wrong with your driver from Brother because I do not use such a driver.
If there is a problem with the driver, then it must be that it has a problem with CUPS from openSUSE 11.1, since as I said, I've used the same driver with the same printer in the last few (open)SUSE releases without such a problem. But again, maybe it was just a strange temporary glitch, since it's now working fine again.
Kind Regards Johannes Meixner
