Exception-Reporting Codes
The following tables describe all printer exception codes that are returned to the host in the special data
area of a NACK.
Each exception code is identified by three bytes: byte 0, byte 1, and byte 19. The first table lists the
names of the exception classes which are returned in byte 0. The subsequent tables give detailed
information about each of the groups listed in the first table.
• The printer provides an approximate count of occurrences of some exceptions.
