When I configured my new 2018 Mac Mini last year I encountered no problems in getting my HP laser printer, LaserJet 2100, and Epson scanner, Perfection V37, functioning flawlessly. After I upgraded to Mojave 10.14.3 both devices ceased to function. At this point in time I've only attempted to reconfigure the printer, the Mac recognizes it but the printouts consist of one line of garbled characters. For the record, yes, the printer is ancient, 20 years old, it's only on its third toner cartridge, but it still functions flawlessly on my old iMac and Windows PC. The scanner is six years old and it too functions flawlessly on my old iMac and Windows PC. I'm currently using Mojave 10.14.4 hence, I haven't upgraded to 10.14.5, I'm skeptical of doing so as to not to lose anymore functionality. Apple hasn't explicitly stated that there are any printer fixes in this release. Any ideas?
