Copy character set from ROM to RAM
ASCII ESC : 0 0 0
Hexadecimal 1B 3A 30 30 30
Decimal 27 58 0 0 0
Default: Current active ROM code page
Copies characters in the active ROM set to RAM. Use this command to re-initialize the user-dened character set. Code
page 437 is copied by default at initialization.
This command is ignored if current font is the user font.
Related information
To modify characters in one of the character set variations, such as rotated print, select one of the rotated print commands,
copy to RAM, then use the dene user-dened character set command (1B 26).
Cancel user-dened character
ASCII ESC ? n
Hexadecimal 1B 3F n
Decimal 27 63 n
Value of n: Specied character code.
Range of n: 32–255
Cancels the pattern dened for the character code specied by n. After the user-dened character is canceled, the
corresponding pattern from current active ROM code page is printed.
Exceptions
This command is ignored if n is out of range or if the user-dened character is not dened.
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
signicant bit, LSB)
Range of n: 0-255
Default: 0 (O)
Starts or stops emphasized printing. The printer is reset to the standard print mode after a clear printer (0x10) command is
received.
Exceptions
Only the lowest bit of n is effective. Emphasized printing cannot be used with bit-images or downloaded bit-images.
Related information
This command and the select print mode(s) command (1B 21) function identically. They should have the same setting
when used together.
In A793 emulation, this command is unrecognized and the parameter byte is put into the print buffer.
