My HP deskjet printer is hooked up to a Windows XP computer in which file and print sharing is enabled. Also the printer itself has sharing enabled and this serves as my network printer. After several hours I finally got the network printer to show up on my Windows 8 laptop and successfully print a test page. It is also showing under Devices and Printers and all looks good. The problem is that it doesn't show up as a "printer" option on any programs/apps that allow printing. I tried Notepad to test the printer and my network printer was not there. I also tried several other programs with no luck. Any ideas? Thanks!
