Character set selection
The document printer prints characters as dot patterns. The data for the dot pat-
terns of the characters is stored in the ROM (Read Only Memory) of the printer.
If the printer receives a character code from the computer, it prints the corre-
sponding character according to the stored pattern.
Two areas are differentiated with the printable character codes:
area with the basic characters or italic characters
area with the italic characters or graphics and special characters.
To differentiate the character code areas thefollowinglabelsareusedinthis
chapter:
’lower control code table’ for the code range from hex 00 to hex 1F (decimal
0to31)
’lower character table’ for the code range from hex 20 to hex 7F (decimal 32
to 127)
’upper control code table’ for the code range from hex 80 to hex 9F (decimal
128 to 159)
’upper character table’ for the code range from hex A0 to hex FF (decimal
160 to 255)
’complete upper character table’ for the code range from hex 80 to hex FF
(decimal 128 to 255).
The following character set definitions result from this:
The ’italic character set’ contains basic characters in the lower character ta-
ble and italic characters in the upper character table
The ’graphics character set’ contains basic characters in the lower character
table and graphics characters in the upper character table
The ’extended graphics set’ contains a basic character set in the lower cha-
racter table and graphics characters in the complete upper character table.
