Macbook Air 2019 can't connect to HP printer
My MacBook Air seems suddenly (it worked for months before, prior to the last couple of OS updates) unable to set up our HP 7800 series all-in-one printer. I have done the reset in System Preferences and for the most part (with odd exceptions where it works for awhile) the reset gets hung up while trying to connect to the printer (which it does recognize as being there) and doesn't complete. I have restarted, and on a couple of occasions have then been able to access the printer directly from the app (e.g. Quicken). Even if I get the printer to respond normally that lasts a short time; it then goes to waiting a half hour to execute a print command; then drops entirely. The perplexing thing is that my wife, with identical computer and sitting next to me, has no problem printing, which would seem to rule out network or wifi issues. I must be missing something obvious, but what? Catalina version 10.15.4.
