+5 V @ 0.75 A - FET Circuit current limited
The maximum current available through the serial port, USB port, or both will not exceed a total of 0.75 Amps.
When XON/XOFF handshaking is selected in the printer driver, the data flow is controlled by the ASCII control codes DC1 (XON) and DC3 (XOFF). The DTR control lead will have no effect.
Connecting the Printer to a DTE Device
Shows a printer to DTE device connection diagrams.
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.
Connecting the Printer to a DCE Device
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.
