Chapter 7: Downloadable Fonts
The printer allows the user to download their own fonts and store the fonts in either volatile
RAM memory, or non-volatile FLASH memory.
7.1 FLASH Data Types
The printer’s FLASH memory provides non-volatile storage for several types of data:
1) 120 FLASH memory banks are 64Kbyte sectors for storing
downloadable FONTS and GRAPHICS, using TCI #7.
These FONTS are downloaded using the ^D135 command.
These GRAPHICS are downloaded using the ^D133 command.
(See Chapter 6, Downloadable GRAPHICS.)
2) 128 slots for label FORMATS.
These FORMATS are downloaded using the ^D130 command.
3) 7 “embedded” FONTS. These FONTS are downloaded at the factory.
NOTE: The printer’s FLASH memory retains data after power is turned OFF. So data that
is downloaded to the printer’s FLASH memory will be available until erased by the user.
FONTS & GRAPHICS stored in FLASH memory are accessed using TCI #7 and the
appropriate slot # (CGN #).
7.2 RAM Data Types
The printer’s RAM memory provides volatile storage for several types of downloadable data:
1) RAM memory slots #1 thru #255 are used to store downloadable
FONTS and GRAPHICS using TCI #8.
These FONTS are downloaded using the ^D127 command.
These GRAPHICS are downloaded using the ^D107 command.
(See Chapter 7, Downloadable GRAPHICS.)
2) 128 slots for label FORMATS.
These FORMATS are downloaded using the ^D59 command.
NOTE: The printer’s RAM memory is NOT battery backed-up. So when the printer is
turned OFF any data stored in the RAM memory is lost. The downloaded data that is stored
in RAM is temporary.
7.3 Using the Font Conversion Utilities
The printer treats downloadable fonts just like the standard bitmapped font mentioned in
Chapter 5. TrueType® fonts can be converted using the “Fontcv16.exe” software utilities.
Downloadable font fields use the same structure as the bit mapped fields with the only
difference being that the TCI must be set to an “8” for volatile downloadable fonts and the
CGN refers to the memory slot location of the downloaded font. Nonvolatile fonts are
accessed thru TCI “7”.
The following section details the process required to convert and download fonts to the
printer. The conversion utilities “Fontcv16.exe” may be downloaded at
