Intermec Fingerprint 6.13 – Programmer's Guide
NASC
The NASC statement is used to select a character set that decides
how the various ASCII characters transmitted from the host
1
will be
printed. This instruction makes it possible to adapt the printer to
various national standards. By default, ASCII characters will be
printed according to the Roman 8 character set.
Suppose you order the printer to print the character ASCII 124 dec.
If you check the character set tables at the end of the Fingerprint
6.13 Reference Manual, you will see that ASCII 124 will generate
the character “|” according to the Roman 8 character set, “ù”
according to the French character set and ñ according to the Spanish
set etc. The same applies to a number of special national characters,
whereas digits 0–9 and characters A–Z, a–z plus most punctuation
marks are the same in all sets. Select the set that best matches your
data equipment and printout requirements.
If none of the sets matches your requirements exactly, select the one
that comes closest. Then, you can make final corrections by means
of MAP statements, see above.
A NASC statement will have the following consequences:
• Text printing
Text on labels etc. will be printed according to the selected
character set. However, instructions that already has been processed
before the NASC statement is executed, will not be affected. This
implies that labels may be multilingual.
• LCD display
New messages in the display will be affected by a preceding
NASC statement. However, a message that is already displayed
will not be updated automatically. The display is able to show
most printable characters.
• Communication
Data transmitted from the printer via any of the communication
channels will not be affected, as the data is defined by ASCII
values, not as alphanumeric characters. The active character set
of the receiving unit will decide the graphic presentation of the
input data, e.g. on the screen of the host.
• Bar code printing
The pattern of the bars reflects the ASCII values of the input data
and is not affected by a NASC statement. The bar code interpretation
(i.e. the human readable characters below the bar pattern) is
affected by a NASC statement. However, the interpretation of bar
codes, that have been processed and are stored in the print buffer,
before the NASC statement is executed, will not be affected.
