You need to check with HP to see if your HP LaserJet 1018 is supported in Catalina. Catalina will only run 64 bit apps, however, most drivers are already written for 64 bit. I can tell you that my ancient HP LaserJet 1012 (which is older than your 1018) works just fine with Catalina. Chances are your 1018 will too.Colour me amazed. I had a heckuva time getting our ancient 1012 running with my office iMac (2009 vintage) - had to modify some linux drivers to make it work, and even then it was hit-or-miss, and this was under Sierra (? - it's been awhile, certainly not one of the newer macOSes).
Kudos to you! I know there is some sort of issue with Catalina and drivers. Is it possible to run an HP Laserjet 1018 on MacOS Catalina? It's an older HP Printer.There are a number of open source drivers for the HPLJ 1018. Check out:If your printer supports Postscript, you may be able to get by using a generic Postscript printer driver.There should be a driver included with Catalina called: “Generic Postscript PPD”. Try it.If worse comes to worse, you can purchase a commercial driver for your printer:Printfab ($56).
