Cancel user-defined character

ASCII	ESC ? n
Hexadecimal	1B 3F n
Decimal	27 63 n
Value of n:	Specified character code.
Range of n:	32–255

Cancels the pattern defined for the character code specified by n. After the user-defined character is canceled, the corresponding pattern from code page 437 is printed.

Exceptions

This command is ignored if n is out of range or if the user-defined character is not defined.

Select or cancel emphasized mode

ASCII	ESC E n
Hexadecimal	1B 45 n
Decimal	27 69 n
Value of n:	0	(bit 0) not selected
	1	(bit 0) selected
	(When 0 and 1 are the least
	significant bit, LSB)
Range of n:	0–255
Default:	0	(bit 0)

Starts or stops emphasized printing on slip and receipt.

In emphasized mode on the slip, each line is printed twice to improve penetration of multi-part 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.

Exceptions

Only the lowest bit of n is effective.

Emphasized printing cannot be used with bit-images or downloaded bit-images.

Turns double-strike mode on for the slip station. Overprints a second pass of the print line on the slip station to improve penetration of multi-part forms and increase print contract. The second pass is printed the same direction as the first to ensure accuracy of the overprint. The printer is reset to the standard print mode after a clear printer (0×10) command is received.
