- Load Font Equivalence.

If the following terminating conditions occur, the printer returns to home state and reports the

indicated exception:

– An asynchronous exception occurs such that the printer cannot recover without host intervention.

The asynchronous exception is reported and the exception that caused the skip and continue

action is discarded.

– A command is received with the ARQ flag set on. The exception that caused the skip and

continue action is reported.

– A command is received with a length outside the valid IPDS range. The exception that caused

the skip and continue action is reported.

– A command is received that violates the IPDS state diagram. The exception that caused the skip

and continue action is reported.

During skip and continue actions, Any-state commands are treated as follows:

– SHS and XOA-DBD are next valid commands in all cases. They are processed, the skip and

continue action processing is terminated, the exception is reported, and normal command

processing resumes.

– Any-state commands with the ARQ bit set on are terminating conditions. They are not processed;

they terminate skip and continue processing, the exception is reported, and the printer returns to

home state.

– All other Any-state commands are processed as normal. However, subsequent non-Any-state,

non-next valid commands are skipped.

Exceptions detected in included overlays or page segments are treated as though the commands

were received as part of the page.

v Bit 7: Error Page Print

If both bits 6 and 7 are set to 1, bit 7 is ignored. If bit 6 is 0 and bit 7 is 1, the printer prints as much of

the page as possible and returns to home state.
