^HT - Host Linked Font List
Sends the list of linked fonts back to the host.
^HT returns the printer's font-link table over the link. A font link makes a base
font default to a second font for characters it does not contain, and ^CW sets one
up. ^HT reports the links in place. Its printed counterpart is ^LF, and the
difference decides this page: ^HT renders no page, and ^LF renders one.
Syntax
^HTSupport
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 font links ^LF would print, but over the printer's link, so it renders no page. This service holds no font-link table to describe. 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
^HT takes no arguments.
Behavior
^HT postdates the 2006 edition of the ZPL II Programming Guide and appears nowhere
in it, so the guide documents no reply layout. Labelary's description says only that
^HT requests a list of font links through the terminal.
The renderer holds no font-link table and no link to answer on, so it ignores the
command. Measured against Labelary on 2026-07-30:
^XA^FO50,50^A0N,40,40^FDhi^FS^HT^XZ returns X-Total-Count: 1. Labelary renders no
page for ^HT either, so the two engines agree. The renderer reports
IGNORED_COMMAND at info severity, which does not reach X-Warnings. Labelary is
also silent.
Example
A format that asks for the font links and prints a line of text. Only the text reaches the page.
