Font Loading Command Functions
Introduction
The commands used for font loading are usually generated by font creation software;
however, the assigned font ID number command must be sent to the printer before the font
file. All Font Loading Commands begin with
<ESC>
(ASCII control character
27
[decimal]).
The downloaded font will be stored in the default module (refer to the
<STX>X
command) as
file type .dbm. The commands in the table below are listed in their order of appearance, top
to bottom, during font downloading. The
<SOH>D
command must be sent prior to
downloading a font.
