8.3 Alternate Protocols Supported by the LA310 MultiPrinter
This part of the manual describes the DEC PPL2 protocol as implemented on
the LA310 MultiPrinter. The LA310 MultiPrinter also emulates the protocols
for printing on the following devices:
• IBM Proprinter III
• Epson FX-1050
The protocol mode is changed using either the Select Other Coding System
(SOCS)/Return from Other Coding System (ROCS) command combination or
the IBM Proprinter Emulation Mode (DECIPEM) command. These commands
are described in the Command Dictionary.
Table 8–3 lists the SOCS/ROCS command sequence to enter emulation mode
for each of the protocols supported by the LA310 MultiPrinter.
