Function	Reset horizontal and vertical tab stops
ASCII	[ESC] R
Hexadecimal	1BH 52H
Decimal	<27> <82>
IPCL	&%HV
EPOS	none

Description This command resets horizontal and vertical tab stops to power up configuration. The power up horizontal default is every 8 spaces, i.e., 9, 17, 25, etc. The vertical default is every line.

Function	Set justification
ASCII	[ESC] a <n>
Hexadecimal	1BH 61H <n>
Decimal	<27> <97> <n>
IPCL	&%JL, &%JC, &%JR
EPOS	[ESC] a <n>
Description	This command sets the horizontal justification.
Where <n>	0	= left justified	&%JL
	1	= center justified	&%JC
	2	= right justified	&%JR

The print format can be right, center, or left justified. The value of <n> specifies the justification.

The power on default is left justified.

Note: Lines that have mixed size characters cannot be centered. For example, a line with mixed single- and double-high cannot be centered. If

aline of print is to be double-high and centered, the change to single-high must be done after the line terminator for the double-high line.

Example: [ESC] W <3> Centered [ESC] W <0> [CR] will not print correctly because the printer assumes that more data will follow the [ESC] W <0>. This should be [ESC] W <3> Centered [CR] [ESC] W <0>.

Note: Several line graphic characters stress the printer. If the printer is to print a very dark area, it will do it in steps. The stepping operation only works in left justified mode. In general, this will not cause a problem because the printer will print several black blocks in a row before the stepping program is activated. Autocenter and line graphics should be avoided because of character alignment.

Note: Justify commands do not affect graphics.
