Printing very slow after converting to network from USB printing

My problem is similar to the previous post, though not identical so I started
a new thread.

I am using an HP 2200 printer on my home network - 3 PCs all running XP
Home. The printer was networked and working fine until I had to change
things about a bit at home. I was temporaliy using the HP as a local USB
printer for a few days whilst I was getting the ethernet cabling sorted to my
new office. Once that was finished I reconnected it as a network printer
again.

Problem is that now printing is taking 10-20 mins, even though I can access
the web-based admin interface on the printer no problem. I have noticed
though that after printing svchost service is hogging memory resources until
the print job completes.

Computer is 2.8GHx Celeron with 896Mb RAM, so RAM shouldn't be an issue.

Any ideas?

Thanks
