I recently built a new Core i5 system with Windows 7 Professional. I had planned to hook up my old HP Deskjet 816c printer using a USB to parallel cable (Link Depot).
Once I plug the cable in, Windows 7 recognizes it as an IEEE-1284 controller and automatically installs the appropriate driver. However, in the status window it reports the following:
"USB Printing Support -- Ready to use"
"No Printer Attached -- Ready to use"
When I then go ahead and manually add the printer using the "virtual printer port for USB" I can add the printer seemingly without problem. Once finished, it appears in the Devices and Printers panel. Yet, all attempts to print on this printer fail. It appears that simply no data is sent to the printer (either by programs like word or adobe or by attempting to print a test page.
