LocalTalk (AppleTalk compatible), Ethernet (TCP/IP, IPX/SPX, and EtherTalk corresponding), and IrDA (infrared
adapter), are offered.
The PrintPartner 20W comes standard with the HP LaserJet 5 emulation and the PostScript level 2 compatible

1.7 Environment Friendly
The PrintPartner 20W uses a toner recycle mechanism that does not generate toner waste. This means that the
printer uses toner effectively and the operator does not need to deal with wasted toner.
The power-saving design (intelligent heater on/off sensing) reduces power consumption.
Ozone emission is low.
Plastic parts are marked with the plastic content for ease of product recycling.
The user-selectable economy mode extends the lifetime of the toner bottle.
