Printing and scanning problem on HP DeskJet 2700

Answer 1

You're asking about 2 problems: print, and scan.

Print is managed via CUPS (Common Unix Printing System), browse to http://localhost:631 to manage/add your printer. Read man -k cups.

Scanners are accessed through SANE (Scanner Access Now Easy). Read man -k sane, especially man sane-find-scanner
