be interpreted accordingly. For more information, see the description of the command set
horizontal and vertical minimum motion units command (1D 50) in this document.
Compatibility information (TH210 receipt vs. A793 receipt)
There is a difference in the normal behavior of this command in A793 emulation mode as
compared to the original A793. The difference exists when the command is used to move to the
left. The A793 processes the whole print string prior to putting it in the buffer for the printhead.
This method of processing allows the A793 to back up in the print string and replace characters
and their associated attributes when a “Set relative print position” command instructs the printer
to move the print position to the left.
In order to improve the speed of printing, theTH210 moves the data into a buffer for the printhead
when it receives it. When the “Set relative print position” command contains a move to the left,
this causes the new data to overstrike the previous data. This behavior can be used to an
application’s advantage to provide the ability to create compound characters on the receipt
station.
This command also functions differently in the A793 emulation when used in graphics:
n x 2 = Number of dots to be moved from the beginning of the line when this command is
followed by a graphics command.
Set vertical line spacing to 1/6 inch
ASCII ESC 2
Hexadecimal 1B 32
Decimal 27 50
Range of n : 3.33 mm (0.13 inch)
Sets the default line spacing to 4.25 mm (1/6 of an inch).
This is set independently of the vertical motion unit (see 1D 50 x y).
Set vertical line spacing
ASCII ESC 3 n
Hexadecimal 1B 33 n
Decimal 27 51 n
Value of n : n /406 inch in Native mode
n /360 inch in A793 emulation mode
n/203 inch in Application Compatible
Escape Commands emulation mode
Range of n : 0-255
Default: 3.37 mm (0.13 inch)
Sets the line spacing to n/16 mm (n/406 inch). Note: sending 1B 32 will overwrite this setting.
The minimum line spacing is 8.5 lines per inch. The line spacing equals the character height when n
is too small.
If the set horizontal and vertical minimum motion units command (1D 50) is used to change the
horizontal and vertical minimum motion unit, the parameters of this command (set line spacing)
will be interpreted accordingly.
