Since purchasing a new laptop running Windows 7 and Adobe Reader X, I'm having trouble with my printer (HP P2005dn) driver. When I print a .pdf file that has mixed media (some pages 8.5 x 11 mixed with 8.5 x 14), the content of the bottom fourth of the legal size docs does not print. This happens every time the first page in the file is letter size.

I've tried to "fool" the printer and tell it to print one of the legal size pages first, then print the entire file (15, 1-144). In that case, the whole content does print on the legal pages, but it "corrupts" the top of at least one or two of the susequent letter size pages (puts a black streak across the top).

I have reloaded the software numerous times to no avail - the problem persists.
Any suggestions? Is there a compatibility issue with Windows 7 or Adobe X?
