Hp laserjet 3600 PCL XL error when printing a PDF

I'm using an hp laserjet 3600 and just recently started receiving a PCL XL error when printing a PDF. I've had th printer for well over a year and just recently started having this issue. I uninstalled and reinstalled and it was fixed for a day or so. It's connected directly to my desktop (no network), my OS is Windows XP pro. I can print from other programs...it seems to be specific to Adobe Acrobat Reader...using version Reader 8.

I've read about the PCL5 vs PCL6 but was not able to successfully use a PCL5 driver for this printer. Any help is greatly apprciated
