Certain applications won't print

I recently bought a Toshiba Laptop with Windows 7 Home Premium. I have a HP Photosmart 3100 connected via USB to my iMac which is running Snow Leopard.
I've installed the printer in Windows with no problems. Certain applications, like Firefox and Windows Live Mail, can print with no problems. Other applications, like Quickbooks Easystart 2010 and Adobe Reader, can't print at all. I try to print a PDF in Adobe Reader, and it sends it to the printer like everything is fine, but the printer just sits idle as if nothing has been sent. No error messages, it just doesn't print. I've tried reinstalling the printer in Windows, but obviously it didn't help.

Any assistance would be greatly appreciated.
