User-defined NASC tables
A user-defined NASC table can be used in place of one of the built-
in NASC settings. It specifies a unicode for each of the 256 ASCII
characters, and determines the mapping of single-byte codes in text
fields and human readable parts of bar codes. A user-defined NASC
table is specified using the command:
NASC "<file name>"
<file name>
the name of a file containing a user-defined
NASC table.
Default:
NASC 1 (the built-in Roman 8 NASC table is
used)
Such a file can be created using some text editors, or by a user-
written piece of software. It can be sent to the printer using the
FILE& LOAD
command (see page 65) or copied onto a MSDOS
formatted memory card which can be inserted in one of the printer's
PCMCIA slots. It is a binary file 516 bytes long, with the following
format:
Byte 0:
N
Byte 1:
S
Byte 2:
C
Byte 3:
1
Byte 4:
high byte of unicode for ASCII 0
Byte 5:
low byte of unicode for ASCII 0
Byte 6:
high byte of unicode for ASCII 1
Byte 7:
low byte of unicode for ASCII 1
