@PJL USTATUS JOB <CR><LF>START<CR><LF>[NAME=<job name><CR><LF>]<FF>
The printer resets the nested job counter whenever it switches the source to a different I/O channel.
This prevents a corrupt job on one channel from disrupting the activities on another channel.
@PJL EOJ
This command identifies the end of a print job and is a hint for the I/O switching algorithm. The printer
counts nested jobs and recognizes job boundaries when the counter decrements to zero. The printer
ignores isolated EOJ commands. Each EOJ must be preceded by a JOB command.
@PJL ECHO
This printer supports the ECHO command, which transmits its parameters over the I/O channel to the
host that issued the command.
@PJL USTATUS JOB=ON/OFF
This command enables or disables the JOB status for the I/O channel that delivers the command.
@PJL USTATUSOFF
This command disables the unsolicited JOB status for the I/O channel that delivered the command. For
this printer, it duplicates the function of @PJL USTATUS JOB=OFF, AND @PJL USTATUS
DEVICE=OFF.
NOTE All commands that this printer's PJL command set does not support are returned with
the message @PJL xxxx<CR><LF>?<CR><LF>.
