Black's the workhorse. Every invoice, every memo, every 'please print this by 3pm' runs on it first. When that cartridge dies mid-run, the whole office feels it. This is the HP 937E Black – the high-yield version, part #4S6W9NA. More pages per swap, less time hunting for a replacement. It's sitting in our warehouse now. Grab it before your next print queue backs up
