Printing using 100% CPU

What is the fix for this problem for disk drivers? Is there an error
counter I can check? It is an Epson 1270 although I've noticed this with
other printers as well. It is the "System" process which is using all the
CPU.

It would be part of the motherboard utilities package, so look on the
website of the motherboard manufacturer.

Remember also that the PC is now very much faster than it was when the
parallel port came into existance.... so printing a complex document through
the parallel port goes through a tight bottleneck. Your CPU can send the
data really quickly, but if it gets stuck going through the port at snail
speed, there is nothing much your CPU can do except sit and wait. The
obvious solution is to purchase a USB 2.0 printer.

I was just thinking how wonderful life was, when "Charles P. Lamb"

It depends on the printer driver and settings. Get the latest driver
is you haven't already.

I could not fix this using an Epson 750 photo printer...I had to
change the printer.

Charles/Ted: forgive me for butting in... but I believe he is looking at
the
Performance Tab on task manager and Ted you possibly are looking at the
processes tab.

The performance tab shows cpu usage as a %.

My XP home edition (sp2 current updates) when sitting with OE and IE
windows open shows 2-3% cpu usage.
Sounds like he has something odd going on or a misbehaved app.

Charles: If this just started: anything recent you can uninstall try a
restore point from a couple or so weeks ago?
I'm no expert on his! That's just what I"d do.

Regards to all,
Dallas...
