Font Selection - Epson GQ-3500 User Manual

Not all fonts are available in both orientations. Be sure that the
typeface you want is available in the desired orientation by checking
the label on the download font software or IC card. Three of the
internal fonts (Courier 10, EDP 13, and Extended Graphics) canbe
printed in either orientation.
The command to change the orientation is ESC o, followed by a
number specifying the desired orientation: 0 for portrait or 1 for
landscape. To change to landscape orientation, the BASIC command is:
LPRINT CHR$(27);"o";CHR$(l)
To change back to portrait orientation, you can use the orientation
command again (replacing the 1 with a 0), use the control panel (see
Chapter 3), or use the printer initialization command. The
initialization command, which is ESC @, resets the printer to its
normal settings for such items as orientation, font, margins, and line
spacing. To use the command in BASIC, enter the following:
LPRINT CHR$(27);"@"
The initial settings reset by ESC @ are also affected by the
settings of the DIP switches.

Font Selection

If you have any IC font cartridges or user-defined (download) fonts
for your GQ-3500, you have a wide variety of typestyles and sizes
available to enhance the appearance of your printed documents. Even
without these options, however, the GQ-3500 has many print
variations.
You use the ESC y command followed by two numbers to select a
typeface. The first number specifies the group of fonts you want to
for internal fonts, 1 for IC card fonts, or 2 for user-defined fonts. The
second number identifies the specific font within the selected group.
The following program shows how the ESC y command can be used to
choose any of the four internal fonts available in portrait orientation.
