Notes:
1. If the entire resource list does not fit in the Special Data Area of the Acknowledge Reply, continuation is
necessary which the S828 Printer will indicate using the Acknowledgement Continuation bit in the flag byte of
the Acknowledge Reply. If the host requests Acknowledgement Continuation by sending a command with
ARQ bit and the Continuation bit set, the printer will complete the RRL reply using Acknowledgement
Continuation. If the host requests RRL continuation (by sending an RRL command with nonzero values in
bytes 3 and 4), the printer will use continuation, the printer will default to RRL continuation.
2. For overlays, segments, and symbol sets, this is their two byte ID. This field is omitted when the resource
type equals All.

Exception Handling Control (EHC)
An exception (error) exists when the printer detects an invalid or unsupported command, control, or
parameter value in the data stream received from the host. The IPDS structure provides Alternate
Exception Action (AEA) when the printer receives a valid parameter value, but the printer does not support
this value. The Exception Handling Control subcommand allows the host control of exception handling by
the printer. This subcommand specifies the action the printer is to take with respect to the reporting and
processing of exception (error) conditions. The format of the EHC subcommand is:
Decimal Hex Value Description
0-1 0-1 F600 EHC Order Code
