Bug 803325

Applications->Administration->printing

shows no local printers; file->connect pointed at the printer host by its IP address shows all four printers, but 'lpstat' still continues to ignore them.

When you ran the troubleshooter did it offer you the opportunity to save a 'troubleshoot.txt' file on the final screen?  That file would be useful to look at.

You need to start system-config-firewall and allow 'Network Printing Client (IPP)'.

Sadly, although that does bring some improvement, it doesn't actually get printing to happen.

I disabled the firewall altogether (just to be sure) for the moment and LibreOffice and lpstat can now see all four print queues on the network server.  I can generate print requests from LO or lpr at the command line, but they never leave the laptop.  No log entries appear on the network server and no paper is disgorged from any printer.

Here  is the /var/log/cups/access_log, showing a couple of attempts to use
'lpr' to print files:

Here is /var/log/cups/error-log

and the output of 'lpq -a'

The printer icon appears on the screen and shows all three print requests
with the status 'Not Connected', so in the attached .tgz file are the
'c' files from /var/spool/cups

TGZ of the 'c' files from /var/spool/cups

These are the three c0000* files from /var/spool/cups showing the status of the print jobs on the laptop.

Please run the troubleshooter again and attach the new troubleshoot.txt file you get.

text file from printer troubleshooting

Output file from printers->help->troubleshoot as requested.

Upon boot, the previous c* and d* files in /var/spool/cups had been removed.  I did "ls -la | lpr -PP2015" in /var/spool/cups and a d* file appeared containing the "ls" output as plain text; no c* file.  I then tasked trouble shooting about the print queue.  It could see all four printers, so I selected P2015 and followed through to text output (it enabled debugging on the way).  It reported that there were status messages associated with this printer: can't find printer.
Detailed output attached.

Thanks.  The client machine is not able to resolve the hostname of the print server.

What does 'ping purse.barumtrading.co.uk' say?

'ping' says:

and to anticipate your next question, /etc/hosts contains:

OK, sorry - I've just seen and fixed that problem.  I put an '@' rather than a '.' as the first delimited in the full machine name.  Setting the '.' in place correctly solves the problem.  Sorry to have taken up so much of your time.
