EFP9800 ESC/POS Commands

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.
