Cups Unable To Open Device File /dev/lp0 Permission Denied

The problem appears to bewith how CUPS handles the USB->parallel conversion, or perhaps it isin the HAL configuration. Imagine that-- 3 drivers just to print something!) Since you need a special driver, it matters whether your Linux distro has it or not.So if you've got CentOS 5.3, and a LinuxQuestions.org > Blogs > ted_chou12 parallel port with cups (LPT) User Name Remember Me?

Is this fixed in sid? I love this printer. System is slackware 12.2 kernel 2.6.27.7 cups 1.3.9 Last edited by agentrnge; 01-20-2009 at 07:19 PM.. D [04/Jun/2005:19:27:18 +0200] LoadDevices: Added device "parallel:/dev/lp0"...

Additionally, CUPS (and the print screen for Firefox, oddly enough) have a message after the name of the printer that reads: "Unable to open parallel port device file: Permission denied". I hope posting here after the bug report was closed isn't a no-no.

At this point you will get the /dev/lp0 node. (You won't get any /dev/usb/ nodes, and you don't need them.)Then create a CUPS entry for your parallel printer, using "parallel:/dev/lp0" as http://popupjammer.com/cups-unable/cups-unable-to-open-print-file-permission-denied.html Full text and rfc822 format available.

Luk, please note that "parallel" != "cups-pdf". :-) With 0755 root:root, the backends are run as lp:lp, so I wonder why the backend cannot access /dev/lp if it is 0660 root:lp.

usb bus, pci bus, memory access, port access, reading out device ids, reading out vendor stings, reading out capabilities ...So now the kernel knows how to communicate with the device but Copy sent to Debian CUPS Maintainers . sudo vim /etc/group that didn't work though.. Toggle useless messagesView this report as an mbox folder, status mbox, maintainer mbox Report forwarded to [email protected], Debian CUPS Maintainers : Bug#462149; Package cupsys.

The workaround for me is changing "cnijusb:/dev/usblp0" to "file:///dev/usblp0" in /etc/cups/printers.conf, and then adding "FileDevice Yes" to /etc/cups/cupsd.conf. so for the meantime, i'm leaving the group of /dev/usb/lp0 as "lp" until I can figure it out.
