FONT LOADING COMMANDS
These commands are utilized to send bitmap fonts to the printer. 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.
