Strange cups/enscript behaviour, protection problem?
I have just re-installed cups on a SuSE V9.2 Linux system. User root can print, other users can't; to be more precise, I get a printout as user root, but not when logged in as a non-root. Yet when I check the cups error log, it looks as if the jobs are getting printed. (see the entries in cups error.log below). Observing the printers, in both cases, there is data being sent to the printer (activity light starts flashing). In both situations, I attempt to print the same text file using enscript -P fs_1010_net filename.txt. The printer is a kyocera fs_1010 printer with a network port, configured as direct port printing to port 9100. What goes wrong? cups or enscript? Thanks for any clues.

Which makes sense because regardless which user submits a job to the printing system, the processes of the printing system run always under the same user "lp".

Regarding CUPS, see http://portal.suse.com/sdb/en/2002/11/jsmeix_print-cups-options.html Regarding enscript: Try the same as normal user when you did before export LC_ALL="POSIX" export LANG="POSIX" If it works then, it is a problem caused by the normal locale setting of this user which may somehow cause enscript to produce either PostScript which the printer does not understand or the well known error that in a locale where the decimal point is a comma the PostScript also contains commas instead of decimal points which would result a syntax error in the PostScript interpreter. To verify print as normal under the normal locale with enscript into a file (e.g. echo Hello | enscript ...) and grep for ','.

Thanks, Johannes You pointed me in the right direction. I used enscript -p to create the postscript file as root and as normal user and then compared the two outputs. The only difference is that root creates an A4 page, whereas non-root users create a letter size page. The kyocera fs-1010 network printer is set to A4 and does not print letter size pages, it just does nothing, i.e. flushes the data. I tried the same with a hp laserjet, which prints both, a4 and letter, so the problem appears to be caused by a particularity of the printer. Thanks for your help. Peter

Have a look at both printer's manuals. Often you can set for paper selection something like "automatic" or "nearest size which fits" or "automated scaling" or "fall back to A4" or similar stuff. I assume the Kyocera prompts for Letter paper (watch the printer's display) and after a timeout it discards the job because what else could the printer do if it is set to print only on exact matching paper except waiting infinite which would block subsequent printouts.
