Good luck. 
Sorry but my problem is not that it is not recognized but that it won’t print. In fact, it states that it has printed (test page), but it did not engage the printer. I have already installed two other printers, one wireless (Brother Laser) and one direct (HP DeskJet) and they print out test page but just not this (favorite) HP LaserJet 1000 ( I know it is a 32 bit printer and very old but It only works with Linux and now will not work with this new Linux 1804.

I have no experience with this software. Good luck.
