B
Comparison of DEC PPL2 Commands by
Printer
Appendix B compares the DEC PPL2 commands supported by the Digital Level
2 printers. The LA50, a Level 1 printer, is included for reference.
Each command is described as belonging to a level of the protocol or an
extension to the protocol.
Each level of the protocol includes the commands of the lower-numbered levels
of the protocol. Therefore, level 2 of the protocol (DEC PPL2) includes the
commands of level 1 (DEC PPL1).
Table B–1 compares the DEC PPL2 commands as implemented on each
type of printer.
Table B–2 compares commands that are extensions to the protocol.
Table B–3 compares commands that are exceptions to the protocol.
Table B–4 compares the printers’ alternative protocol capabilities.
