XES COMMAND LANGUAGE MODE

This section discusses the data encoding systems, or coding schemes, supported on the 4213 printer, how to load a table of characters using the Character Reassignment command, and how to switch from one table to another using the Language command.

The actual language code mappings are found in Appendix A.

Other tables needed for character assignments are in appendix

D, ªReference tables.º

Supported coding schemes

Tables D-2, D-3, and D-4 in appendix D list the coding schemes supported by the 4213 printer: ASCII, ISO, and EBCDIC. The ISO coding scheme has been derived by the International Organisation for Standardisation and is intended for use in international markets. Note that the ASCII code set is essentially a subset of the ISO set.

Control codes

Table D-1 lists control codes (with hex value less than 20 in ASCII or ISO; less than 40 in EBCDIC) that are meaningful to the 4213 printer, their most common uses in those environments, and the ways in which the printer responds to them.

7-bit coding schemes

Non-EBCDIC hosts may transmit 7-bit codes to the 4213 printer; however, 7-bit coding schemes are normally unable to invoke font characters whose assigned code has a value greater than 7FH (the primary code set). Most fonts have some characters within the range 80H to FFH (the secondary code set). Multinational character mapping uses characters in the range 80H to FFH to construct a language specific, 7-bit mapping table that includes all standard national language characters.
