EF4270 Emulation Commands

Reset Printer

This command is processed immediately and causes the printer to reset and initialize as if the power had been interrupted. All data in the buffer will be lost. The printer sends an XOFF if XON/XOFF handshaking is selected.

No additional data should be sent to the printer following the reset command until one of the following:

•The BUSY line toggles (parallel interface).

•The RTS line toggles (RS-232 serial interface with RTS/CTS hardware handshaking selected).

•The printer sends an XON (RS-232 serial interface with XON/XOFF handshaking selected).

If the unit is configured for XON/XOFF serial interface handshaking, the printer also toggles the RTS line in addition to sending the XOFF/XON.

The printer reinitializes with the default DIP switch settings.
