Do not connect printers via wireless, that is not reliable. Connect directly to your modem via Ethernet or via USB.
Avoid inkjet printers if color is not needed. Black and White Laser printers are the way to go for maximum reliability and low cost per page.

If you do purchase an inkjet printer, print one test page once a week. If your printer is idle for to long, the print heads dry out and clog up, especially in winter in cold country and in summers in hot climates.
