5.6 Working with loadable fonts
Loading a font
The command is used for loading additional fonts in the printer. The
loadable fonts may contain from 1 to 256 symbols not necessarily
arranged in a fixed order. You can create your own fonts using the
syntax of the command described further on or you may use ready
programs for the purpose - for example Soft Font Downloader Utility.

5.5 Working with graphic files
Loading a new graphic
Saves a new graphic file in the memory of the printer. The rules con-
cerning names are the same as with the forms. The command will be
rejected if there is a graphic file of that name or the entered size of the
file is greater than the size of the free operational memory. The file
must be in the PCX format, monochrome - in any other case it will not
be loaded. It can be produced in different programs under Windows
- for example PhotoShop.
Format: GM”Name”,n
Name: The name under which the graphic file will be
saved in the memory of the printer.
n The length of the file (not more than 32768 bytes).
After the command the set quantity of bytes must
be sent to the printer.
Example: GM”Logo1",3530
The saving of a graphic file under the name “LOGO1” will
begin (with a length of 3530 bytes).
Drawing out of a graphic file

of the printer under that name.
