Extended Graphics/High Resolution Commands
In Extended Graphics/High Resolution Mode, you can access the extended
graphics commands as well as new commands designed to achieve
enhanced resolution for thermal printing. This mode allows you to specify
graphic elements and characters in expanded size and position parameters.
Graphic elements (lines, boxes, and forms) can now be defined in increments
of one thousandth of an inch. Characters can now be specified in increments
of one hundredth of an inch. As a result of these enhancements, you can print
forms and labels that include high resolution text, graphics and bar codes.

The actual positioning and size, however, can be only as "fine" as your printer
resolution (dpi). For example, a graphic position change of 0.001, 0.002, or
0.003 would result in one printer dot at 300 dpi (1 - .0033 inches). Also,
because the actual height of characters change in increments of seven printer
dots (0.0233 inches at 300 dpi), a size specification of 0.01 inch or 0.02 inch
would result in a character of the same size.

To enable Extended Graphics/High Resolution Mode, you must have already
enabled Graphics Mode through use of the ^PY command. You cannot
enable the Extended Graphics/High Resolution Mode, however, from within a
graphics pass (an alphanumeric command, ^M, ^E, ^U, or ^V).

VGL initially operates in normal resolution mode. To switch between normal
and high resolution, send the appropriate command shown above, or use the
"Cmd Resolution" option on the front panel menu.

You can switch between normal and high resolution between graphics passes
