An example: Proportional bold extended looks good as a title. To get it you
add up the n values for those three (2 + 8 + 32 = 42), and send the command:
<ESc>!42
Subscripts and superscripts
Subscript mode prints characters at half of the normal height, in the lower
part of the line space. Superscript mode prints characters at half of the normal
height, but in the upper part of the line space. You may want subscripts and
superscripts for footnote numbers or mathematical formulas. The only
restriction is that you can’t use subscripts and superscripts with double-strike
mode.
You switch to subscript or superscript mode with this command:
<ESC> S n
in which if you make n any even number you get superscript mode, and if you
make n any odd number you get subscript mode.
You cancel subscript or superscript mode with this command:
<ESC> T
How to cancel a line or delete a character
When you’re printing you sometimes send a line, but then change your mind
and don’t want to print it after all. The Cancel control code lets you erase from
your printer’s memory just the last line you sent. (If you cancel a line you will
also cancel the extended print mode if you’ve been using it.)
By sending this command you make your printer cancel all the characters you
have sent since the last carriage return or line feed:
<CAN>
Sometimes you want to delete from the printer’s memory, before the page
gets printed, just the last character you have sent. Don’t confuse deleting a
character with backspacing, which doesn’t erase anything from memory.
This control code deletes only the last character sent:
<DEL>
