I've been a long-time user of FinePrint and I'm happy with it but following the glowing comments about priPrinter, I thought I'd give it a try.
Unfortunately, my experiences differ from the positive reports here. The beta version just wouldn't run at all, hanging the prog when invoking a print job (this on a recently reinstalled system running XP SP3 with 1mb RAM). Uninstalling the beta and running the production version was not much better. Sloooow performance - and I've found it impossible to paginate a booklet to print in the correct order on an HP Deskjet and Kyocera laser.
Printing web page graphics seems a major issue with this release. Either they don't appear at all on the print preview or they are replaced with a strange solid black banner type box. Switching back to FinePrint, these anomalies disappear. This might be an issue with Opera, however.
So, priPrinter uninstalled and solidly backto FinePrint.
