I can't get network printing to work. My network printer is an HP2100 residing at 10.10.10.4. It prints from a number of other machines on the network. I can't figure out how to set up printing from my A1. Do I use IPP or SMB? Where do specify the IP address of the printer? I'm a complete novice at this; can anyone point me to a primer on the subject? Google has betrayed me.
