^HH - Configuration Label Return
Sends the printer's configuration back to the host as text.
^HH returns the printer's configuration as text over the link, for a terminal
emulator. It covers the same settings that ~WC puts on a label: darkness,
tear-off, media handling, communication settings, firmware version. ^HH renders no
page, so it cannot change the output of a render request.
Syntax
^HHSupport
Accepted and skipped, because it configures the printer rather than the label. It cannot change the rendered output, and Labelary skips it too.
Returns the same settings ~WC prints, but over the printer's link instead of onto a label, so it renders no page and cannot change the label. 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. — not pinned by a test
Labelary renders this command.
Parameters
^HH takes no arguments.
Behavior
^HH is a ^ command, so the printer processes it in the order it appears in the
format, not on arrival. That order is all it shares with the drawing commands around
it: it has no field, no origin and no output.
The renderer ignores the command, and the page is unchanged. It reports
IGNORED_COMMAND at info severity, which does not reach X-Warnings. Labelary is
also silent, so the label is identical in both engines. None of those printer
settings exist here: the print resolution and the label dimensions are request
parameters, and a render carries only the configuration state the format sets.
Example
Sending it alongside real content changes nothing about the page.
