~WQ - Write Query
Asks the printer to report the state of its RFID subsystem.
~WQ asks the printer to report on its RFID subsystem — the state of the radio
and its counters — over the host channel. It is a diagnostic, sent between formats
and not inside one, and it draws nothing.
Syntax
~WQSupport
Accepted and skipped, because it configures the printer rather than the label. It cannot change the rendered output, and Labelary skips it too.
A host query about the radio and its counters. It returns text over the host channel and draws nothing. The renderer does not parse this command. It reports IGNORED_COMMAND at info severity, which does not reach X-Warnings. Labelary is also silent, so the rendered label is identical in both engines and with or without the command. Neither Labelary's command reference nor the 2006 ZPL II Programming Guide documents this command, so this page publishes no parameter table rather than a guess. — not pinned by a test
Labelary renders this command.
Parameters
~WQ takes no arguments.
Behavior
Neither the 2006 edition of the ZPL II guide nor Labelary's command reference documents this command, so this page publishes no parameter table instead of a guessed one. Labelary's own command table lists it as supported and accepts it silently.
~RO resets the counters that ~WQ reports. Nothing about a query reaches the
label image, and there is no printer state and no host channel here for it to act
on.
Example
A status query ahead of the format it precedes:
