My HP LaserJet 4240n keeps printing 2 blank pages before every print job.
So if you try to print a page from Microsoft Word and it's a one page document, it will print 3 pages -- 2 blank and 1 real page with ink. It will also do this from a PDF and from Wxcel. I have a feeling that this has to do with the printer and not the applications (NOT sure).
I am using Windows 7 (64-Bit)
Printer: HP LaserJet 4240n
Driver installed: Universal Print Driver PCL 6 (printer-specific driver not available on the HP site).
I have also updated the firmware which didn't fix problem.
