EF4270 Emulation Commands

Buffer Clear

Clears all print characters and control codes from the buffer. All current settings are maintained. This command does not return the printer to its default condition. The command is processed immediately.

Hexadecimal Decimal ASCII

1B 60 27 96 ESC ‘

Repeat Character

Repeats any printable characters or control codes up to 255 times. This command is best used to send several Line Feed commands (0A), or to print a single character a certain number of times.

Hexadecimal	Decimal	ASCII	Value of c	Value of n
1F c n n n 1F	31 c n n n 31	US c n n n US	Control Code	30-39	Hexadecimal
			or Character	48-57	Decimal
				0-9 (ASCII)

To send 101 Line Feed commands, send the following string:

1F 0A 31 30 31 1F

where 1F starts the command, 0A indicates the Line Feed command, 31 (Hex) equals ASCII 1, 30 (Hex) equals ASCII 0, 31 (Hex) equals ASCII 1 (thus 101 indicates the number of times to repeat the Line Feed command), 1F stops the command.

Wait for Slip

Puts the printer into slip waiting mode. The Slip In LED blinks until a slip is inserted or the waiting is cancelled. When a slip is detected by both sensors, the printer delays for a few seconds, and then closes the forms assembly. The delay is determined by the Clamp Delay (1B 4C) command. Printing begins 0.18 inches from the top of the form. If concurrent feed is selected, both the cut sheet and the paper roll feed.
