Data Specifications
When communicating via the serial data port (RS-232), the baud
rate, number of data bits, and the parity are user-selectable (see
Section 4 for acceptable setting combinations). Parity only
applies to data transmitted by the printer, since it ignores the parity
of received data. The M-Series Printer is fixed at 1 stop bit, so
make sure that your host is also set at 1 stop bit.
When communicating via the parallel port, the previously
mentioned parameters are not considered.
RS-232 Serial Data Port
The connections for the standard interface are made through the
DB25S connector on the rear panel. For all RS-232 input and output
signals, the M-Series Printer follows both the Electronics Industries
Association’s (EIA) RS-232 and the Consultative Committee for
International Telegraph and Telephone (CCITT) V.24 standard
signal level specifications.
