Chapter 5. IPDS Exception Reporting Codes
The following tables contain the exception reporting codes, which the printer sends to the host in the
NACK reply. These codes are in a three-byte format. The first byte, byte 0, is the error group. The
remaining two bytes, bytes 1 and 2, are the individual error identifiers. Table 8 shows the error group
meanings:
