Are you having a problem with your printer under the latest versions of Ubuntu (perhaps it worked under an older version)? Are you able to print short documents, but not longer, or more graphics-intensive, documents? (e.g. the unfortunate people at http:\/\/ubuntuforums.org\/showthread.php?t=625493<\/a>). Do they sit there as Processing for ages and then switch to Held? If you have the same problem I had the solution I tried may work for you too. Firstly, check your cups error log: <\/p>\n

sudo gedit \/var\/log\/cups\/error_lo<\/code>g<\/p>\n

If you see anything like the following, the solution may be simple:<\/p>\n

[Job 201] Unable to write print data: Broken pipe
\nPID 13359 (\/usr\/lib\/cups\/backend\/socket) stopped with status 1!<\/code><\/p>\n

System > Administration > Printing and right click on your printer, selecting Properties. Settings > Device URI
\nIf you see something like socket:\/\/your_printer_ip_address:9100 just change socket to lpd and remove the :9100 off the end. Then click on apply.<\/p>\n

Apparently lpd is a more modern protocol which works with most printers whereas socket is more raw (and potentially faster but riskier in a network situation). Somewhere along the line, the default Ubuntu\/Gnome setup for networked printers shifted from lpd to socket. Some primitive printers will have benefited whereas a larger number of more modern printers will have suffered.<\/p>\n

Please correct me if I am wrong (which is highly possible) but the underlying problem could be that socket may make the printer wait a long time for a large file to be processed ready for printing. Some printers, such as the Fuji Xerox DocuPrint C525A, may drop the socket if things take too long to start coming through.<\/p>\n

Changing timeout settings might work but lpd is better than socket so it is the preferred solution in any case.<\/p>\n

If this works for you, please leave a comment to let others know (ideally with a description of the printer and Ubuntu version). Printer may be relevant if it doesn’t support the direct stream protocol properly. NB I may take a while to let your comment through because of the volume of spam. Sorry about that.<\/p>\n

Finally, thanks to sphilli8 for the steer in the right direction at http:\/\/ubuntuforums.org\/showthread.php?p=6245626<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
