How do I get my HP Photosmart C4780 to work wirelessly?
I cannot find drivers for my HP Photosmart C4780
printer. It shows up on my MacBook OS 10.13, and I can only connect with USB. The printer's wireless light is lit. I want to connect wirelessly.
MacBook Pro (13-inch, Late 2016, 2 TBT3), macOS High Sierra (10.13.6)
