Vertical and horizontal positioning
The horizontal positioning commands control the horizontal print positions of characters on the receipt.
The commands describe operation for 80mm paper. If the printer supports 82.5mm paper, the dot spacing is the same but
there are 640 printable dots rather than 576 printable dots on the 80mm paper.
Horizontal tab
ASCII HT
Hexadecimal 09
Decimal 9
Moves the print position to the next tab position set by the set horizontal tab positions (1B 44 n1 n2 ... 00) command. The
print position is reset to column one after each line.
Tab treats the left margin as column one, therefore changes to the left margin will move the tab positions.
When no tabs are defined to the right of the current position, or if the next tab is past the right margin, line feed is
executed. HT has no effect in page mode.
Print initialization sets 32 tabs at column 9, 17, 25…
Set horizontal and vertical minimum motion units
ASCII GS P x y
Hexadecimal 1D 50 x y
Decimal 29 80 x y
Value of x: Horizontal
Value of y: Vertical
Range of x: 0 – 255
Range of y: 0 – 255
Default of x: 203
Default of y: 203
Sets the horizontal and vertical motion units to 1/x inch and 1/y inch respectively.
When x or y is set to 0, the default setting for that motion unit is used.
Set column
ASCII ESC DC4 n
Hexadecimal 1B 14 n
Decimal 27 20 n
Value of n: 1 – 44 = Standard pitch
1 – 56 = Compressed pitch
Default of n: 1
Prints the first character of the next print line in column n. It must be sent for each line not printed at column one. The
value of n is set to one after each line.
Exceptions
This command cannot be used with single- or double-density graphics.
