My LaserJet 4P gave hit or miss results when fed by a USB to Parallel cable connector.
I'd shifted over to that rig when I needed to print from a laptop.
When you get to HP's own ancient drivers web support you'll find that HP never wrote their code for anything other than the old parallel printer port. ( of Centronics fame )
So, for anyone that still has a parallel printer port -- you'll get perfect results with HP's official last release -- IF you have a parallel port connection to your LaserJet printer.
This dictum holds for essentially all Ubuntu/ Linux Mint operating systems.http://hplipopensource.com/hplip-web/su ... index.htmlhttp://hplipopensource.com/hplip-web/su ... erjet.html
This solution didn't even require Terminal/ Command Line efforts.
The drivers are factory originals from HP -- machine by machine. No fussing around.
