@jimav, how much exactly does it slow down printing? In milliseconds? I have a problem that seems similar. After recent upgrade to CUPS 1.5.3, my HP LJ 4L connected via USB adapter printing what looks like command leftovers from previous job before printing the next job - judging from
# lpstat -p printer HPLJ4L is idle. enabled since Tue 06 Oct 2015 09:17:09 PM MSK Sending data to printer. (the job is just finished, all fine et al, but printer driver seems to be stuck in some "sending".) All jobs correctly printed, but the paper waste is, of course, undesirable. # lsusb Bus 003 Device 004: ID 1a86:7584 QinHeng Electronics CH340S ... # lpadmin -p HPLJ4L -o usb-unidir-default=true did not helped. # lpadmin -p HPLJ4L -o usb-no-reattach-default=true seems to have done the trick. lpstat still shows the printer stuck in "Sending data", but jobs now coming out correctly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/872483 Title: laser printer only prints first job correct To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/872483/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
