Hi,
have you applied SP1 and all Updates on your XP ?
do you clean up your PC regularly:
- empty TIF=IE-Cache & Temp-folders
- RegCleaning once in a while, especially after Software deinstallation
- Do/did you ever have Norton AV installed on your PC ? Remove ANY traces left of it
Are there any alerts/messages by avast when you print ? Any error messages from the system ? please list more details

P.S.: Avast is free for home&private use, but you have to register it (for free) to extend the license over the trial period
