Hello!
I recently updated all my computers to Windows 10 and now I have a problem that none of my Windows 10 computers can print anymore. Before the update my computers were running Windows 7 where printing worked just fine. I have now tried many different computers, from different manufacturers, all running Windows 10, x86 and x64 versions, none works.
The printer is HP LaserJet 4300n, connected via parallel port (LPT). Since everything worked before Win10 update I must conclude that the hardware is intact and this is a problem in Windows 10, maybe something with the old LPT printer port support.
When connecting the printer, Windows recognizes the device, automatically installs drivers for it, and shows that it is connected. So everything looks good this far.
But the printer does not print. If I print something, e.g. a test page from printers settings, I can see very briefly how the file is put into the print queue, from where it disappears quickly. No print, no errors, no any messages. Also, nothing happens on the printer's LCD screen while sent to printer, and there is nothing in the printer's error log.
