H Block graphics characters and special symbols
Besides the upper and lower case letters and symbols that we are by now familiar with, your printer has a whole different set of characters that are for special uses. These characters include block graphics for drawing forms and graphs, and special symbols for mathematical, engineering and professional uses. The special characters are included in two character sets. The character set you normally use with the IBM mode is called character set #l. The special ch’aracters are printed out when you send ASCII codes 160- 255 to the printer.
Your printer also offers character set #2 which is almost the same as character set #1 except for the addition of ASCII codes 3 h 6, 21, and 128 N 159. Character set #2 is selected with
<ESC > “6”; to go back to character set #l, use < ESC > “7.”
