Extended Graphics/High Resolution Mode; Configuring Vgl With The Control Panel - Printronix L7032 Programmer's Reference Manual

Extended Graphics/High Resolution Mode

Extended Graphics/High Resolution Mode
Within Graphics Mode, there is an additional high resolution mode called
Extended Graphics/High Resolution Mode. In this mode, you can access the
extended graphics commands as well as new commands designed to achieve
enhanced resolution for thermal printing .
Extended Graphics/High Resolution 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 changes 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.

Configuring VGL With The Control Panel

Matching certain printer operational settings to those of the host computer is
known as printer configuration. The settings, or configuration parameters,
such as selecting the host interface, parallel/serial data input and file
management, are adjusted according to the printer function switch
descriptions in your printer's User's Manual . Configure VGL in the same way
you would configure the printer for other features.
You can select VGL default parameters directly from the control panel as
explained in your User's Manual , or by control codes as explained in the
"Commands" chapter. Your User's Manual also contains detailed
configuration menus and diagrams, as well as descriptions of each
configuration parameter available with your printer.
