[nflug] Print Queue ID

[Robert F. Stockdale IV]

I know the symptoms are painful. I have the 895cse and don't use it any more. My daughter will 
if she can't get to the network printer for some reason. But the cost of the print cartridges 
almost on a monthly basis lead me to get a laser printer. What CUPS is doing is first 
converting your document to a postscript format, which takes a lot of processor/memory and io. 
This is usually done through ghostscript. It then pipes that output through the printer driver 
to send instructions to the printer that it will understand. Adding Kprint manager just adds 
another layer of overhead, not to mention you probably now have two print dialog boxes to click 
on to get printing started with many applications. I've also thought kprint was quite buggy. 
There are other kde apps I feel that way about so I don't use kde
I believe if you restart cupsd the print jobs start over. Don't know for sure with kprint also 
running. The first 2 things I'd consider are 1.) dump kprint. You don't need the additional 
overhead. 2.) consider building a print server out of an old computer to off load the print 
processing from your workstation.(or you could upgrade your printer).
Have you tried running top in a xterm prior to issuing the print command?  That could direct 
you to what cups is calling. I believe if you print from the shell or a script a gui print 
manager doesn't intercept the print command.
JUST SOME THOUGHTS
