ABSTRACT:
A printer that contains printer devices that use different versions of a protocol is configured with a translation layer in printer firmware that receives one version of a protocol command from a sending device, translates the protocol command to another version of the protocol command, and sends the translated command to a receiving device or devices. The translation layer includes a table of modified commands that identifies each command used in the versions of the protocol used by the printer devices. The table of modified commands is used to generate a translation table for each device. The translation table is used to find a command that is compatible with a receiving device when the receiving device uses a different version of the command than the sending device. If the command has not changed in the protocol versions used by the sending and receiving devices, then the translation facility is not invoked and print processing proceeds normally.
