SEM — Set Emulation Mode
Format
SEM mode;
Parameter
mode:
0 = Line Printer
1 = IBM Proprinter X-24E
2 = Diablo 630
5 = Epson LQ-850
6 = HP LaserJet/PCL
8 = KC-GL (Plotter)
9 = KPDL (an option on some models)
Function
The SEM command temporarily changes the printing system’s emulation mode. The new
mode remains in effect until another SEM or an RES (reset) command is issued.
The SEM command also resets the margins and various other parameters. It should
therefore be placed at the beginning of a program or file.
The SEM command does not change the power-up emulation mode. When power is
switched off, the printing system loses the mode set by the SEM command. Upon power
up, it retains the default emulation, which is set by the P1 parameter of the FRPO
command.
If you usually work in ‘emulation A’ but occasionally use ‘emulation B,’ it is convenient
to set ‘emulation A’ with the FRPO command and use the SEM command to change to
‘emulation B’ when necessary. In this case you must avoid using the RES command in
‘emulation B,’ because the RES command resets the printing system to ‘emulation A.’
