Character Printing
Print data sent to the printer consist of two types of character codes:
• Printable Characters are codes representing alphabet characters,
punctuation marks, and graphic symbols
• Control Codes are one or more bytes that instruct the printer how to
process and print characters and graphics
The LG06 and LG12 process the character codes of the DEC Multinational
Character Set (shown on page 7–5). Characters and codes from this chart are
identified and located by their column and row numbers. For example, the
ASCII character SUB is identified as 1/10, which means that it is located at
column 1 row 10).
You may send data from the host computer in either 7–bit or 8–bit form.
(The conversion processes from 7–bit to 8–bit form and vice versa are
described on page 7–11.)
Printable Characters
Columns 0 through 7 of the DEC Multinational Character Set (page 7–5), are
the standard ASCII printable character set used in a 7–bit environment. If
you choose an 8–bit environment, the printable character set expands to
include columns 8 through 15.
