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.
