Printer Controlling
NOTE: The information given in this section refers to MS-DOS environment
as it is the most widely-used. For other environments the same logic remains
true, but see the related documentation for details.
The indications given here are sufficient for MS-DOS up to release 6.0.
Parallel Interface
With the resident parallel interface, you do not have to do anything, as the only
variable parameter is the data format "word length", which, in the PC, is
always set to 8. This is the printer's default setting.
The parallel communication protocol can be activated using the following MS-
DOS command (consult your MS-DOS manual for the complete syntax):
MODE LPT1:(characters per line),(line spacing),P
To address the parallel printer interface as a logical output device, you can use
one of the following names: LPT1 or PRN. It is also possible to redirect output
prepared for the parallel interface to a serial interface, using the command:
MODE LPT1:=COMn:
Serial Interface
If you install the optional serial interface in your printer, to use it you must pair
up the printer's protocol with the one in your computer. The protocol can either
be programmed in the printer (for the parameters and programming procedure,
see the specific sections in this chapter), or you can adapt your computer to the
printer setting using the command:
MODE COMn:(baud),(parity),(word length),(stop bits),p
where "n" is the number (usually 1) of the addressed interface board, and baud
requires only a two digit number.
