Creating Downloadable Fonts
5.4.1. Downloading
You can download existing fonts (that is, ones that you have bought or ones that you have created previously)
using either a font downloading application program or the DOS command
COPY/b <filename> PRN
In addition, some word-processing and DeskTop publishing programs will automatically download the fonts
that have been used in a document when that document is printed.
Alternatively, you can create a new downloadable font and download the necessary blocks of data that comprise
the downloadable font using PCL commands.
To send a font, you must send
* a font descriptor block followed by the character code
* a character descriptor
* data for each character
The printer can download 3 types of fonts.
Bitmap fonts, Bound Scalable fonts and Unbound Scalable fonts.
5.4.2. Sending the font descriptor
Esc)s#W (font descriptor data) (27)(40)(115)#(58)
<1Bh><28h><73h>#<88h>
• This command sends the font descriptor to the printer.
• # should be in the range 0 to 32767.
• # is the number of bytes in the descriptor.
• Characters are designed on a notional grid known as the character cell. The positioning and shape of each
character on the grid defines its size, shape and alignment to the other characters in the font.
