Bug#664538: cups: Printing is very slow (100% CPU usage by gs)

[yvan.masson@openmailbox.org]

Hi,

I am facing a similar problem with Wheezy :
  - print from LibreOffice from backports
  - gs process uses 100% CPU
  - takes long time to finish the gs process (approximately 10 minutes 
for 47 pages without pictures, with AMD Athlon(tm) 64 Processor 3000+)
  - when finally the pages are sent to the printer, the first page 
printed contains two lines of strange things, and then the printer 
prints blank pages endlessly.

I faced this with two printers : Epson EPL-N3000 and Epson EPL-N6200, 
both connected by USB. This did not seem to happen with small documents 
(one or two pages).

I then tried to share the EPL-N3000 via LPD on our 2003 server : the 
problem disappeared (gs runs approximately for 10 seconds for the same 
47 pages document).

I have 12 other computers (same models, same softwares, connected to 
another EPL-N3000 via LPD on another 2003 server), and this problem 
never happenned, at least as I know.

It might be related to USB...
If you need more informations, please email me.


Thanks for your time and work,
Yvan Masson
