Master Select - Epson LQ-800 User Manual

To print this combination, therefore, you use ESCape "!" followed
by the number
mand is
CHR$(27)"!"CHR$(l60).
To try this number or any other, enter and run this short program,
which will ask you for a Master Select number and then give you a
sample of printing using that code.
10 INPUT "Master Select number";M
20 LPRINT CHR$(27)"!"CHR$(M)
30
LPRINT "This sample uses"
40 LPRINT "Master Select number";M
50
LPRINT CHR$(27)"@"
In this program, you can use any number you calculate by using the
formula above, but remember that proportional can't be combined
with elite. If you try to combine proportional with elite, you won't
harm your printer; proportional will simply override elite.
In the printout below you can see the result of using the number 96
with this program:

Master Select is a powerful code that gives you an easy way to
produce multiple combinations with a single command. To produce
double-strike emphasized underlined printing, for example, you need
only one ESCape code instead of three.
Indeed, Master Select is such a powerful feature that it may occa-
sionally be more powerful than you want it to be. Because it controls
nine different modes, a Master Select code will cancel any of those
nine that are not selected. For example, suppose that you have a page
in elite and want part of it underlined. If you use ESCape "!" 128 to
turn on underlining, your LQ will begin printing in underlined pica
instead of underlined elite because the 128 code does not include elite.
Use 129 for underlined elite or use ESCape "-1" to turn on underlin-
ing.
If you want to use Master Select with the fifteen mode, you must
send the Master Select code before you send the command for fifteen
mode (Escape "g"). If the fifteen mode command is sent first, Master
Select will override it.
