HP 4050 Printer Error: 79.EEFE

[Daniel Kasak]

Hi all.

I just switched our printer setup from Samba ==> CUPS to direct IPP 
printing ( Windows clients connect via an address like 
http://servername:631/printers/printername ).

With the old setup ( via samba ) we had no problems with our HP 4050.

Now, though, when a certain document ( Excel ) is printed, we often get 
an error on the printer's LCD:

79.EEFE
PRINTER ERROR

I've checked http://www.advancedlaser.net/errorcode/error_79.htm and it 
indicates that it could be a software / driver issue, which I tend to 
agree with. It's not hardware problem, as when I print through samba it 
works fine.

The document is a very simple invoice, with Tray 1 selected ( manual 
feed ). The default is tray 2.

The only way to get the printer working again is to power cycle it. When 
the power is off, I 'stop' the printer via the CUPS web admin page, and 
when the printer is turned back on and has finished initialising, I 
'start' the printer again via the web admin page, and the print job 
which previously crashed the printer continues and prints OK ( from the 
right tray too ).

Anyone seen this before?
