6.12 Preprocessing Input Data

All input data to the printer come in binary form via the standard IN
channel (by default "uart1:"). Characters are transmitted in ASCII
format, which upon reception will be preprocessed by the printer's fi rm-
ware according to possible
The instruction is used to modify a character set, or to fi lter out

them as NUL (ASCII 0 dec.).

Example:
You are using the Roman 8 character set with 7- bit communication and
need to print £ characters which are not included in the 7-bit part of that
character set (see Chapter 9). Suppose you have no need for the $ char-
acter. Then remap the £ character (ASCII 187 dec.) to the value of the $
character (ASCII 36 dec.):
