CPU at 100% during printing: why?

    Hi all,

    I have a Compaq Presario600 with AMD Athlon processor, running XP. I have a cheap Canon S820 printer. Everytime I print something, the whole computer slows down because CPU gets maxed out at 100%. :mad: When I sort on processes in Task Manager, it just lists SYSTEM as taking up the resources.

    What is causing this and how can I stop it? A couple of things I am thinking (but I am not sure, so I need your help):
    1. The printer has no memory (hence the cheap price) so the CPU has to send the printing data real time.
    2. Something wrong with the printer driver.
    3. Some stupid 'feature' of XP that does this.
    4. Some stupid setting I have selected that does this.

    Note: this slowdown happens regardless of what I am printing (text or photo) and it lasts for the duration of the printing.

    Any help is appreciated !

    Number 1 is a likely cause. Also, is your printer USB or parallel? If it's parallel, and the parallel port isn't using DMA (i.e. it's SPP, not ECP) then that's why it's using all the CPU power. Use USB if possible.

    How Much Random Access Memory (RAM) do you have?
