Option Feedback
Once enabled, the printer will report information about the results of the last label printed. One
response per label is returned to the host (this includes each voided and retried label). The format and
contents of the returned information is as follows:
Printer response format:
<A;B;C;D;E;F>[CR]
Where:
A
- Device type:
R = RFID
S = Scanner
B
- Resulting status:
C = entire label complete
F = faulted (failed) label
U = unknown
C
- The number of expected reads for bar codes or tags, given in two
characters.
D
- The number of good reads for bar codes or tags, given in two
characters.
E
- The printer’s internal Job Identifier and Sub Job Identifier, given in
four characters each.
F
- The data read, delimited with semicolons (;) if multiple reads.
RFID response samples: Since RFID commands vary in operation, the data returned also differs.
Write commands return entire tag data; Write/Verify commands return the data written; and, Read
commands return data and length requested in the specified format. (See Appendix T for a listing of
commands.)
