+5 V @ 0.75 A fused

The maximum current available through the serial and/or parallel port is not

to exceed a total of 0.75 Amps.

When XON/XOFF handshaking is selected, data flow is controlled by the

ASCII control codes DC1 (XON) and DC3 (XOFF).  The DTR control lead

will have no effect.

Interconnecting to DTE Devices —The printer is configured as data

terminal equipment (DTE).  To connect the printer to other DTE devices

(such as the serial port of a personal computer), use an RS-232 null modem

(crossover) cable.

Interconnecting to DCE Devices —When the printer is connected via its

RS-232 interface to data communication equipment (DCE) such as a

modem, a STANDARD RS-232 (straight-through) interface cable must be

used.
