Reset Advanced Counters
Description Use this command to reset the advanced counters used by the printer to monitor
label generation in inches and centimeters, the number of labels printed, and the number of
valid and voided RFID labels. Any single error during programming of an RFID tag will result
in that label being considered “void” by the counter.
Four resettable counters are available. The values for the counters are displayed on the printer
configuration label.
Format
~ROc
This table identifies the parameters for this format:
Important • This command is not supported by all printers or firmware. See Table 13
on page 287 for the list of printers and firmware with which you can use this command.
Note • For the R4Mplus, the counter values are not saved, so power cycling the printer resets
all counters to zero.
Parameters Details
c = counter to reset Accepted Values:
1 = counter 1
2 = counter 2
3 = valid RFID label counter
4 = voided RFID label counter
Default Value: None. If a value is not specified, the command is ignored.
Example 1 • This example shows how the counter portion of the printer configuration labels
looks when counter 1 is reset by sending
~RO1.
