Printer Queue Testing - How can I run a software printer on my desktop

I wrote a web service to use with my PPC.  The web service sends a print job to a print queue.  It takes quite a bit of paper as you can imagine to test this.

I'd like to set up some type of a software print queue (on my PC) that I can review print jobs etc, and see what they looked like without actually printing a page.

I know you can print to file etc, but that seems difficult to look at and review.  Anyone got a simpler idea... and of course, free is the key.

Thanks!
