It's possible that this might be a duplicate of bug #661814. Here are some more RPM versions on my system, if relevant: foomatic-4.0.5-1.fc14.x86_64 system-config-printer-1.2.5-8.fc14.x86_64 The only reasons PPDs in an existing system would be changed are: * hpijs has been updated, and an existing PPD has ", hpcups" in its NickName attribute, and it doesn't have an hpPrinterLanguage attribute (i.e. it was generated using an older version of hpcups) * gutenprint-cups has been updated, and an existing PPD has a line starting with "*%Gutenprint Filename:", or has one of the attributes StpPPDLocation, StpDriverName, or StpLocale. We shouldn't be changing other PPDs in other situations. (Arguably, we could change foomatic PPDs -- Ubuntu does this -- but I am not in favour of changing existing PPDs unless absolutely necessary.) So let's leave bug #661814 as tracking "wrong default driver for this printer", and this bug can track "existing PPD is changed unexpectedly". I guess we need to try installing Fedora 13, setting up some queues, upgrading to Fedora 14 and verifying what driver they are now using. OK. Unfortunately I can't guarantee that I'm remembering my prior CUPS configuration correctly, so this is a low-reliability bug report. If it looks like the code wouldn't change the CUPS driver, it's very possible my memory is mistaken. Sorry for the poor quality bug report. lpinfo -l -v shows nothing that looks useful to me. I'll attach the output of lpinfo -l -v both before and after changing to Postscript driver (before = pxlmono = very slow printing = what it was before I manually intervened yesterday, after = Postscript = after I manually changed the driver to Postscript). I'll also attach the PPD before and after. And I'll attach some output from the graphical troubleshooter (System >> Administration >> Printing >> Help >> Troubleshoot), which I ran only after changing to Postscript (I don't have this from before I made the change). If you're looking for a Device ID, the following commands gave me more promising output: # /usr/lib/cups/backend/snmp 192.0.0.192 network socket://192.0.0.192 "HP LaserJet 1200" "HP LaserJet 1200" "MFG:Hewlett-Packard;CMD:PJL,MLC,PCL,PCLXL,POSTSCRIPT;MDL:HP LaserJet 1200;CLS:PRINTER;DES:Hewlett-Packard LaserJet 1200;MEM:16MB" "" # /usr/lib/cups/backend/socket network socket "Unknown" "AppSocket/HP JetDirect" This is a HP LaserJet 1200 printer attached to a HP JetDirect device that provides Ethernet connectivity, and then connected by Ethernet.

For the bug report about the pxlmono driver being slow see bug #661814. Summary updated to reflect that. system-config-printer-1.2.6-3.fc14 has been submitted as an update for Fedora 14. https://admin.fedoraproject.org/updates/system-config-printer-1.2.6-3.fc14 system-config-printer-1.2.6-3.fc13 has been submitted as an update for Fedora 13. https://admin.fedoraproject.org/updates/system-config-printer-1.2.6-3.fc13 system-config-printer-1.2.6-3.fc13 has been pushed to the Fedora 13 testing repository. If problems still persist, please make note of it in this bug report. If you want to test the update, you can install it with su -c 'yum --enablerepo=updates-testing update system-config-printer'. You can provide feedback for this update here: https://admin.fedoraproject.org/updates/system-config-printer-1.2.6-3.fc13 There are two things that might explain this: 1. the foomatic-db recommended driver may have changed, after which you may have recreated the queue using the same procedure as before. This would result in a different driver being used. 2. there was a bug in system-config-printer that would cause a different driver to be used than the one selected. system-config-printer-1.2.6-3.fc14 has been pushed to the Fedora 14 stable repository. If problems still persist, please make note of it in this bug report. (In reply to comment #18) > system-config-printer-1.2.6-3.fc14 has been pushed to the Fedora 14 stable > repository. If problems still persist, please make note of it in this bug > report. Still having the problem described in BZ 670089, even with system-config-printer-1.2.6-3.fc14. Trying to print "http://www.rhrk.uni-kl.de" on my lexmark network printer, nothing is printed, and the printer icon remains in the notification area for a lot of minutes, and the network is busy. By changing the driver from pxlmono to ljet4, I get rid of this problem. (In reply to comment #19) > Still having the problem described in BZ 670089, even with > system-config-printer-1.2.6-3.fc14.

Thanks for head up, but as you can see bug #661814 (which is 670089 duplicate of) is still in ASSIGNED state, so yes, we know that the problem is still there (probably foomatic package). AFAIK *this* bug in system-config-printer would cause a different driver to be used than the one selected. system-config-printer-1.2.7-2.fc13 has been pushed to the Fedora 13 stable repository. If problems still persist, please make note of it in this bug report. |
