I can not get stamps.com to print postage. I am using Parallels 4.05, and am able to print from Windows XP programs using the designated HP LAserJet 8500 PS designation. Every program seems to print but stamps.com. Since the LJ 8500 is a new printer for stamps.com purposes, I have to run printing tests. The envelope passes through the printer, but nothing prints on the envelope. No address, nor any postage. If I change to the printer actually connected, HP 2055, the envelope does not even pass through the printer. Any help would be appreciated. I would like to use stamps.com because Indicia d/n print the labels I use. NM
