Diablo 630 Emulation (Mode 2)
7-13
Fonts can be selected by placing font commands in the file to be printed, or using SETF
(set alternate font) and ALTF (change to alternate font) commands. To substitute scalable
fonts for the embedded fonts using SETF command, employ the FSET command to
apply the appropriate font number for that scalable font. The default font mode (FTMD)
is 0, so the printing system will not adjust character spacing, line spacing, or page orien-
tation.
The red/black ribbon feature of the Diablo 630 printer is implemented in an interesting
way. The printing system translates the black ribbon command internally into an ALTF 0
command, and the red ribbon command into an ALTF 1 command. It also uses two pairs
of SETF default values:
Accordingly, if you use the embedded command that asks for red ribbon, you will get
bitmap font 2, Dutch801BM10-Roman, which the printing system emulates using a resi-
dent scalable font. This font is proportionally spaced, so you should also specify propor-
tional spacing with an embedded command. When you change back to black ribbon, the
printing system changes to bitmap font 1, CourierBM12-Roman, also emulated using a
scalable font.
With SETF commands you can select any two fonts you like which correspond to the
black and red ribbons. For example, you can have black mean normal CGTimes and red
mean CGTimes italicized. The appropriate setup is shown below, together with a short
file and the printed result.

For red-ribbon, put ESC A (^[A in binary notation) at the point you would start to print
in normal CGTimes, and put ESC B (^[B in binary notation) at the point to end using the
font.
