Multinational Character Sets 7–7
Accessing Characters and Character Sets
Data Bit 8
You can access individual characters using data bit 8 addressing. The primary
character set is ASCII. These character values reside at hex addresses 20
through 7F. The Multinational or extended character sets reside at hex
addresses 80 through FF and are accessible without reconfiguration.
NOTE: Data bit 8 must be set high so that Multinational or extended
character sets are accessible without reconfiguration.
Power–Up Character Set Selection
You can select any one of the twelve resident multinational character sets
shown in Table 7–1 (0 through 11) as the default character set at printer
power–up. The IGP/PGL configuration settings determine which character
set is the default character set at power–up. Refer to the “Installation and
Configuration” chapter to configure the IGP/PGL for a specific character set.
(See Select Font in the configuration menu.)
The character font selected at power–up will remain active until the ISET
command is selected or the configuration is changed. OCR and
user–definable character sets cannot be configured as the default character
set at printer power–up.
