I have two identical laptops runnung Windows XP. I have installed the HP OfficeJet 6450 wired and wirelessly on both. Wired works fine on both. One works fine wirelessly as well, the other generates an "hpslp@####.log" file about three times per minute and runs the CPU utilization up to 100%.


The "hpslp@####.log" file on the computer that has the problem looks like this:

Try to reinstall the software.

I have deinstalled and reinstalled numerous times with the same result.
