CHAPTER 7: DOWNLOADABLE FONTS
The 412 is capable of storing up to 255 downloadable fonts or graphic images. The printer
treats downloadable fonts just like the standard bit mapped fonts mentioned in chapter 4. Both
LaserJet™ and TrueType® fonts can be converted using the "JET2412.EXE" or
“TTF2MIC.EXE” software utilities. (Note: The "JET2412.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.
7.1 USING THE FONT CONVERSION UTILITIES
The following section details the process required to convert and download fonts. The
conversion utilities may be downloaded at: http://www.microcomcorp.com. These 16 bit DOS
utilities convert font
s from the LaserJet™ SFP or TrueType® TTF formats into a format
suitable for downloading to the 412 printer.
7.1.1 SFP2MIC.EXE PROGRAM
A) Run the program SFP2MIC
B) Follow the on screen instructions and note the slot # the image was placed in.
C) Make sure the slot is clear. Printer memory can be cleared using the ^D100 command.
D) Download resulting file (filename.N12 or .R12) file to printer
E) Section 4.5.3 explains how to access loaded images.
7.1.2 TTF2MIC16.EXE PROGRAM
A) Run the program - TTF2MIC16
B) Follow the on screen instructions and note the slot # the image was placed in.
C) Make sure the slot is clear. Printer memory can be cleared using the ^D100 command.
D) Download resulting file (filename.N12 or .R12) file to printer
E) Section 4.5.3 explains how to access loaded images.
7.2 FONT DOWNLOAD METHODS
The model 412 supports compressed and uncompressed font and graphic image downloads.
The compressed format (^D107) shortens download time by reducing the number of bytes sent
to the printer. Please note that the compressed format is only usable on 8 bit data connections
and will not function using a 7 bit connection. The uncompressed format (^D104) is usable on
7 or 8 bit data connections. This ^D104 method is more flexible but it encodes the image data
using ASCII-HEX. This results in a much larger file size. Microcom Corporation recommends
using the compressed format when possible.
7.2.1 COMPRESSED BINARY IMAGE COMMAND (^D107)
This command allows fonts or graphic images (fonts must be less than 64KB uncompressed)
to be transmitted in binary, thereby cutting the number of bytes sent in half. Furthermore, this
command allows for data compression by converting strings of 0h or FFh bytes to shorter byte-
plus-count sequences. These sequences are expanded to the proper number of bytes within
the printer. This command is only useable on data connections that support 8-bit data such as
a serial port configured for 8 data bits and no parity, or a parallel port. This command will not
function correctly with a serial port configured to 7 data bits.
The following is the format of ^D107 command when used with a graphic image file.
