Printronix P9000 Series - Manual (Page 202)

Multinational Character Sets 10-2
The selection of the Extended Character Set also sets the print mode and pitch at which the
Extended Character Set is printed. The print mode and pitch can be different for the Primary
and Extended Character Sets. However, the Primary Set cannot be mixed with an Extended Set
within the same line if the Extended Set is printing at a different print mode than the Primary
Set.
When ECMA 94 Latin 1 has been selected from the control panel, the OSET command can be
sent from the host to then select the extended portion of the character set. More information
on the OSET command is provided in Character Set Select: ECMA 94 Latin 1 Extended, located
in the Programming chapter.
OCR-A and OCR-B
OCR print modes are selected from the Print Mode feature at the Print Format (Level 1) of the
Configuration Diagram shown in the Configuration chapter.
OCR print modes do not contain complete character sets. (OCR character set charts are loĆ
cated in Appendix B.) Available OCR-A standard characters are dictated by American NaĆ
tional Standard Institute (ANSI) #X3.17-1981, and OCR-A international characters are in
accordance with International Organization for Standardization (ISO) #646-1973. Available
OCR-B standard and extended characters are dictated by ANSI #X3.49-1975. Undefined
OCR characters are replaced with spaces. When an international language substitution is seĆ
lected for a non-existent character, no substitution will occur.
Downloading Languages and Characters
Character substitution tables can be customized and stored until needed using two DownloadĆ
ing procedures. Using the Downloading a Language feature (ESC V) allows you to define and
download a character substitution table which can be placed within the 224 printable symbol
code points. Download a Character, activated by ESC c, allows at least six characters (dependĆ
ing on the character size(s)) to be defined and stored in NOVRAM. Refer to Download a LanĆ
guage and Download a Character in the Programming chapter.
The complete character library is shown in the Character Address Table on page NO TAG. The
character library identifies each character's location in printer memory by its hexadecimal adĆ
dress value (see the Numeric Character listing starting on page 10-6 or the Alphabetical CharĆ
acter listing starting on page 10-18). International language substitutions are retrieved from
this Character Address Table and substituted in the values shown on the international lanĆ
guages substitution tables. For example, while 7E hex is the Lowercase Beta symbol on the inĆ
ternational substitution table for ECMA German, E1 hex is the actual address of this character
in printer memory. All symbols are shown in 10 cpi, and do not represent the symbol in all print
modes and pitches.
NOTE: The character examples provided in each character set are representative and not
exact replications generated by the printer. In addition, not all characters are available in
all print modes.
