Cancel User-Defined Characters
Cancels the user-defined character designated by character code n of the
selected font size. After a particular character is canceled, the corresponding
built-in character is printed. The printer ignores this command if a user-defined
character is not defined for the character code n or if n is out of range.
Hexadecimal Decimal ASCII Value of n
1B 3F n 27 63 n ESC ? n 32 - 126
Set/Cancel Emphasized Mode
Starts or stops emphasized printing. In emphasized mode, each line is printed
twice to improve penetration of multiple forms and increase print contrast. The
second pass is printed the same direction as the first to ensure accuracy of the
overprint. (Printing speed decreases due to the second printing pass.)
Emphasized printing cannot be used with bit-images or downloaded bit-images.
This command and the Select Print Mode(s) command (1B 21) function
identically. They should have the same setting when used together.
Hexadecimal Decimal ASCII Value of n
1B 45 n 27 69 n ESC E n 0 -255
The settings do not apply in page mode.
Note: Only the lowest bit of n is effective. When n is even, emphasized mode
is turned off and when n is odd, emphasized mode is turned on.
