CHAPTER 7: DOWNLOADABLE FONTS
The 48-466 is capable of storing up to 20 downloadable fonts. The printer treats downloadable fonts
just like the standard bit mapped fonts mentioned in chapter 4. You may either purchase
downloadable fonts from Microcom (see section 11.3) or use the Microcom "JET2466.EXE"
software utility to create an 466 file from your own collection of LaserJet II™ compatible fonts. (Note:
The "JET2466.EXE" program uses the Portrait or 0 degree source rotation for both normal and
rotated fonts.)
Downloadable Font fields use the same structure as bit mapped fields. The only difference is that
the TCI must be 8 for downloadable fonts. The CGN refers to the actual downloaded font to be used.
The following is a list of commands referring to downloadable font functions.
^A
^D Command
100 Clear User RAM: This command will clear all downloaded fonts, graphics, and
stored label formats.
101 List Memory Bytes Available: The printer will send a < character followed by the
amount of bytes and finally a > character. (ie. >192680<)
XX 106 Load Font/Graphic Image into User Memory: ^A select which slot to place the
font/image in (1-20).
The following section details the process required to convert and load user defined fonts. The
conversion utility "JET2466.EXE" is available on request. This DOS utility converts fonts from the
popular .SFP format in to a format suitable for downloading to the 466 printer.
7.1 PROCEDURE FOR USING JET2466.EXE UTILITY
A) Type at DOS prompt - JET2466 filename.ext
B) Follow the on screen instructions and note the slot # the image was placed in.
C) Down-load resulting file (filename.N66 or .R66) file to printer
D) Section 4.5.3 explains how to access loaded images.
7.2 FONT STRUCTURE
The following font structure is offered to programmers who with to use their own programs to
convert fonts.
Note: The 48-466 does not differentiate between graphics and fonts. They both are accessed by
using a TCI of 8. Therefore a font and a graphic cannot have the same CGN number. A graphic is
simply a font with only one character and all characters point to the same character.
The 48-466 font structure consists of Microcom LDS commands, a header, a look-up table, a
character descriptor, and character data. All words are in Intel format: low byte, high byte.
The font structure...
^AXX^D1065 ;tells printer that a font is coming, XX is the CGN number;
;Font descriptor
dw
MCS ;maximum cell width in font if 90 or 270 deg
;maximum cell height in font if 0 or 180 deg
dw DCS ;(signed) default character spacing
