Operating Systems Linux Slackware CUPS setup / dev/lp0 perms. ... Slow printing. Post 302278627 by agentrnge on Tuesday 20th of January 2009 06:13:22 PM
Old 01-20-2009
Upon each bootup /dev/lp0 is getting created with permissions to allow root and group lp rw access.

The printer shows unavailable. print jobs error out saying "unable to write to /dev/lp0"

cupsd is running as root
parallel is running as lp

As soon as I add +rw to all users it is fine. This does not feel like the correct "solution".

CUPS-GENPPDUPDATE(8)					      Gutenprint Manual Pages					      CUPS-GENPPDUPDATE(8)

NAME
cups-genppdupdate - update CUPS+Gutenprint PPD files SYNOPSIS
cups-genppdupdate [-h] [-n] [-N] [-q | -v] [-s ppd-directory] [-s output-directory] [PPD-FILES or QUEUES...] DESCRIPTION
cups-genppdupdate regenerates the Gutenprint PPD files in use by CUPS, using the PPD files under /usr/share/cups/model/gutenprint as tem- plates. The new PPD file replaces the old PPD file under /etc/cups/ppd, but all the options set in the old PPD will be merged into the new PPD, provided that they are still valid in the new file. If no files or queue names are specified, cups-genppdupdate updates all Gutenprint PPD files in /etc/cups/ppd. Otherwise, cups-genppdup- date updates all files or queues listed on the command line. cups-genppdupdate does not update Foomatic PPD files or PPD files from Gimp-Print 4.2 or earlier. cups-genppdupdate does not restart cupsd. cupsd will need manually reloading (or send SIGHUP) once cups-genppdupdate has completed. OPTIONS
-h Show a help message. -n No action. The program will run, but the old PPD files will not be replaced. -q Quiet mode. No messages will be issued, apart from errors. -v Verbose mode. More informative messages will be issued. Note that extremely verbose output may be turned on by setting $debug=1 in the source, but this output will not be of use to the average user. -s ppd-directory Use ppd-directory as the base directory to read PPD files from. By default, the base directory is /usr/share/cups/model/gutenprint. Under this directory, the PPD files are located in subdirectories according to language code and territory. -o output-directory Place updated PPD files in output-directory. By default, this is the same as the input directory. -N Reset all options to their defaults (do not merge options from the current PPD file) SEE ALSO
