My last Epson was a LQ500 (24Pin) . . . . . I have a Citizen GSX24 (24Pin) and a HP DeskJet 840C connected to my A2000, and a Canon BjC-1000SP unconnected at this time.
You have THREE choises:
° Choose a Parallel Port printer
° Fit a USB Card to your A3000
or
° Network your A3000 to use a system (with USB) that is connected to a USB-ported printer!

There is one other, but that is a Second-hand printer option!
