Description of problem: Latest CUPS version breaks parallel printing. No printing is possible through a printer on a parallel port. Version-Release number of selected component (if applicable): cups-1.2.12-2.fc7 How reproducible: always Steps to Reproduce: Using either system-config-printer or http://localhost:631 to access the CUPS interface directly, I cannot get anything to print to my HP Laserjet 4000N. This is because the new version, for whatever reason, doesn't accept parallel printers. This problem has just shown up in the latest version. Installed with an "yum -y update". I do not know what the previous version of CUPS was. Actual results: Files go into the printer queue; printer appears to be dead and it does nothing. Expected results: Printer should start printing. Additional info:
Me too. I see there was a udev update about the same time as the cups update and I also see there is no longer a /dev/lp0 device (which is what my printer URL points at), so perhaps this is udev, not cups, but whatever it is, parallel port printing has certainly been hosed by recent updates. I currently have: cups-1.2.12-1.fc7 udev-113-8.fc7 (No, my hardware didn't happen to break at the same time - if I boot windows it can print just fine on the same hardware).
When the printer was working, I'd see this in /var/log/messages: Jul 29 18:32:40 zooty kernel: parport_pc 00:09: reported by Plug and Play ACPI Jul 29 18:32:40 zooty kernel: parport0: PC-style at 0x378 (0x778), irq 7 [PCSPP,TRISTATE] Jul 29 18:32:40 zooty kernel: parport0: Printer, Hewlett-Packard HP LaserJet 6L ...

Now that the printer isn't working, I see this: Aug 7 21:55:58 zooty kernel: parport_pc 00:09: reported by Plug and Play ACPI Aug 7 21:55:58 zooty kernel: parport0: PC-style at 0x378 (0x778), irq 7 [PCSPP,TRISTATE] Aug 7 21:55:58 zooty kernel: parport0: Printer, Hewlett-Packard HP LaserJet 6L ... Aug 7 21:55:58 zooty kernel: firewire_core: created new fw device fw0 (0 config rom retries) Aug 7 21:55:58 zooty kernel: No dock devices found. Just sort of zips right past without mentioning /dev/lp0 anymore.
