I've noticed a *VERY* high CPU usage whenever I print on my IBM PS/2 Model 70.
I'm using a HP Laser Printer with Postscript cartridge connnected to LPT1.
I've got 14 MB of memory.

Under OS/2, one of the CPU meters shows CPU activity up at 40% - 50%
when the spooler is churning output to the printer.  Then, CPU usage
goes down while the printer chugs away, then the usage goes way up again
for the next chunk of data.  During the time, the mouse is quite unresponsive.

Under regular Windows 3.1, not OS/2, it's even worse.  Mouse clicks and
menu choices are ignored for even longer periods of time than with OS/2, so
much so that you can't use Windows at all until the printing stops.

On my COMPAQ 386/33L, which only has Windows 3.1, the machine is perfectly
usage during printing.

Why does this happen, and is there any way to tune the system so the
CPU is usable during the printing?
