0EH — Alternate Character Set Select

0FH— Alternate Character Set Deselect

The printer’s controller board contains two sockets for character set PROMs. One socket is for the primary character set PROM and the other is for the alternate character set PROM. The primary character set PROM usually contains standard characters while the alternate character set PROM may contain special characters.

Alternate and Primary Characters

Alternate and primary characters can be mixed on a single line or printed line–by–line. To select a single alternate character, you must send code 0EH (Shift Out, alternate character set select) followed by the character code, and code 0FH (Shift In, alternate character set deselect), through the host computer. Several single alternate characters with a line also may be selected this way.

Line of Alternate Characters

To select an entire line of alternate characters, you must send code 0EH to select the alternate character set followed by a line of character codes and a line feed through the host computer. This action will print the line, advance the paper, and the printer will default to the primary character set.

If you select the alternate character set when the alternate character set PROM is not installed, a blank space will be inserted each time a character code is received. To alter this situation, the printer must receive the Shift In code or a line feed .
