So I just tried this fix out and it works.
This printer sat on the shelf for a long time unused, because I couldn't see throwing something away that works good except for the lack of a driver
. The XP driver had been thrown about as a fix to make it work in Windows-7 64Bit, but there was a long delay between every page printing with that driver. It was painfully slow.
This HP 3050 PCL5 driver works at normal speed and now I have the use of this printer again. Thanks!
