I am experiencing the same behaviour as wczimmerman described under Ubuntu 12.04. My printer is dot matrix printer (POS printer) Star SP742. If I am trying to print through /dev/parport0 printer is fast and works without any hassles. Otherwise through /dev/lp0 it's very slow and not smooth.
Tested also under openSUSE 12.2 (kernel 3.4.6; doesn't work too) and CentOS 6.3 (kernel 2.6.32 - -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/339752 Title: Slow/stuttering printing through parallel port Status in Ubuntu: Confirmed Bug description: Running current patch level 8.10. Printer is a HP 540 on the parallel port. In CUPS, when selecting the auto detected printer I only have the LPT printer available. Printing to this device using any PPD (HPIJS, PL3, etc) results in slow printing output or, sometimes, even a complete error state on the printer. Booting the same machine up on a LiveCD of Jaunty (Alpha 4) CUPS shows 2 available printers: the first on the LPT port, the second on parport0. Selecting the parport printer (using the hp URI in CUPS) while in the LiveCD allows all printing to function normally. I have verified that all the parport, lp, and ppdev modules are installed.
