When I duplex print a .pdf file, the inside pages print upside down. All other programs print both sides fine (MS Publisher, MS Word, etc.). What do I change to print all pages right-side up? I print on an HP 2506dn laser printer.
If you are printing a pdf, then you are using Adobe Reader or Adobe
Acrobat, please ask in those forums. Off hand, I'd suggest you are just
seeing a funky interaction between Acrobat/Reader and need to see if
there are any settings you can use to overcome your problem. HP Printer
drivers have a history of partial incompatibility with Acrobat.
