Function Characters

(continued)

A single FCN4 toggles between standard and extended ASCII mode for only a single follow- ing data character. This is referred to as shifting into extended ASCII mode or shifting into stan- dard ASCII mode.

Both code sets A and B are needed to represent the entire extended ASCII character set, just as both sets are needed to represent the standard ASCII character set.

FCN4s can be inserted manually, if necessary or desired, by following the syntax described above. The printer will, however, insert them automatically if extended ASCII characters are encountered in the DATA. It will do so in the most efficient manner possible:

·If up to 4 contiguous extended ASCII charac- ters are encountered, it will shift into extended ASCII mode by inserting a single FCN4 be- fore each one;

·If 5 or more contiguous extended ASCII char- acters are encountered, it will latch into ex- tended ASCII mode by inserting two FCN4s before them.

·While latched into extended ASCII mode, it will apply the same rules if standard ASCII

characters are encountered.

Thus, the preferred way to encode extended ASCII characters is to simply embed them in the DATA and let the printer manage the encoding task. For best results, the code set should also not be specified (i.e., p4 = 1). FCN4 s should be manually inserted only in systems where ex- tended ASCII characters cannot be transmitted to the printer.

it is illegal to mix automatic and manual modes within the data for a single symbol; i.e., an extended ASCII character encountered in the data after an will be considered a syntax error. Likewise, an FCN4 af- ter an extended ASCII character will also be consid- ered a syntax error.
