Yes, I have used HP 1020 on my Macs for years, but once I upgraded to Catalina it stopped working. I checked their support page and they have indeed discontinued it, however, I still want to use it as it's the best made printer I've ever owned in my 50 years of life. I'm sure that there are many others out there that would agree with me. I loved it so much I went out and bought used ones years ago, so I have three of the same one making it more important that I get it running again. One is connected to my old iMac 2009 with Lion, another on Windows 10, and the one that won't print is my MBP with Catalina. These printers have saved me soooo much money over the years in not having to buy much printer ink or buy new printers when they break every 3-5 years.
You bring up an interesting point about wireless; no, I have not yet used a wireless connection to print from it, but I think that would be cool to set up once the driver works.
