User-Defined Fonts - Black Box PC124C Installation Manual

After a command string has been defined, activate it by typing the delimiter
(&% or alternate CPT start delimiter) followed by the string number (U0 through
U9) into the document or on the screen. When the document or screen is
printed, the interface will recognize the &%U and send the command assigned to
the string number to the printer.
For example, if command number U1 is assigned to a command string to turn
on shadowed printing (hex codes 1B 28 73 31 32 38 53) for a PCL printer, then
simply enter &%U1 in the document at the point where shadow printing is to
begin.
Some commands, such as emphasized (bold) printing, may continue until
another string is encountered that returns printing to normal, or, for some host
systems, until the next page is sent to the printer.
The interface self-test prints out a list of command numbers and the command
strings assigned to them.

7.3 User-Defined Fonts

The Laser Card supports a vast variety of fonts. For a list of the supported fonts
refer to Appendices A and D. In addition, the User-Defined Fonts feature allows
assignment of new or existing font IDs to different printer resident fonts or fonts
from an optional font cartridge. Up to 10 new pairs of font IDs and fonts can be
created.
The following example assumes the default font is specified as font 11. The font
ID 11 represents the font Courier 10 CPI. If you want to change the default font
but maintain the font ID 11, simply assign a new font to font ID 11 (for example,
Courier bold 10 CPI). This is done by sending the host-download command
&%Z21,0,11(<(12U<(s0p10h12v0s3b4099T) to the printer. Font ID 11 has now
been redefined as Courier bold 10 CPI. Consult the printer's user's guide for the
information needed to write the string.
In the same manner, personalized font IDs can be assigned to printer-resident
fonts or to fonts from an optional font SIMM. These fonts can then be called up
by using the newly assigned font ID, the same way the standard printer-resident
fonts are called up.
User defined fonts cannot be used with the ¬F font change commands.
