[Bug 598919] Re: Slow printer processing for HP Laserjet 2100
Same problem on Canon imageRunner 2200 and Canon imageRunner C2250 using the pxlmono and pxlcolor drivers respectively. Printing documents that are substantially text is OK. Documents containing images can be very slow and the printer sometimes outputs part of the page containing the image and then restarts the whole job from the beginning. Changing from pxlmono to lj4dith resolves the performance problem, but cannot duplex print. The ljet4d driver prints quickly and allows duplex printing. However, it truncates the end of every line slightly. (For example, if the last character on a line is an 'n', this looks like an 'r'.) It therefore appears that the problem is with the pxlmono and pxlcolor drivers. Tracing the output to the printer with Wireshark shows that computer repeatedly sending what appears to be the same output to the printer as per the following sample: 001F4BC8 63 e1 fe 09 e5 03 ff 09 e6 03 f8 42 a0 c0 c2 f8 c... ...B 001F4BD8 09 63 e1 ff 09 e5 03 00 0a e6 03 f8 42 a0 c0 c3 .c..

An eleven-page document with one large image hangs at the page containing the image. After about thirteen minutes, the printer output around a third of the page containing the image and the job restarted from the beginning. As this point I aborted it. The first attempt at printing had output over 30M bytes of data to the printer up to the point at which it failed. The Wireshark trace has been saved, but has not been attached to this report because of its size (11.2M bytes compressed). -- Slow printer processing for HP Laserjet 2100 https://bugs.launchpad.net/bugs/598919 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

We need some more information:
Which applications are you using?
Can you attach error_log files of different jobs as described in "CUPS
error_log" on https://wiki.ubuntu.com/DebuggingPrintingProblems?
While a job is processing, run the command "top" in a terminal window to
see which processes take how much CPU time and how much memory.
Processes owned by the user "lp" (second column, "USER") are parts of
the printing workflow. For the most CPU/memory-consuming processes run
ps auxwww | grep
Replace "" by the actual process number from the "top"
output, first column ("PID"). The output contains the full command line
of the process. Post this output here.
