Table 5-6: Option Feedback Command
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 sample differences: 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.)
Write response example:
<R;C;00;00;0013:0001>[CR]
