HP 5961-0509 manual They may look odd to your readers, Appears normal, Set to default conditions

The character size you specify with SR is a percentage of (P2X – P1X) and (P2Y – P1Y). The printer calculates the actual character width and height from the specified parameters as follows:

actual width = (width parameter/100) x (P2X – P1X) actual height = (height parameter/100) x (P2Y – P1Y)

For example, suppose P1 and P2 are located at (–6956,–4388) and (6956,4388), respectively. If you establish relative sizing and specify a width of 2 and a height of 3.5, the printer determines the actual character size as follows:

width = (2/100) x ( 6956 – (–6956) ) = 278.24 plu or 0.695 cm

height = (3.5/100) x (4388 – ( –4388) ) = 307.16 plu or 0.768 cm

If you changed P1 and P2 settings to (100,100) and (5000,5000), but did not change the SR parameters, the character size would change as follows:

	width = (2/100) x (5000 – 100) = 98 plu or 0.245 cm
	height = (3.5/100) x (5000 – 100) = 171.5 plu or 0.429 cm
	Note that in most languages the width of a letter is typically less than
	the height. If you set your characters to have a different “aspect ratio”,
	they may look odd to your readers.
Note	Either negative SR parameters or switching the relative position of P1
	and P2 produces mirror-images of labels. When P1 is in the lower
	left and P2 is in the upper right, the SR command gives the same
	mirroring results as the SI command. However, if you move P1 to the
	right of P2, characters are mirrored right-to-left; when you move P1
	above P2, characters are mirrored top-to-bottom. When both of these
	situations occur (using negative parameters in the SR command
	with an unusual P1/P2 position) double mirroring may result in either
	direction, in which case the two inversions cancel, and lettering
	appears normal.
	An SR command remains in effect until another SR command is
	executed, an SI command is executed, or the printer is initialized or
	set to default conditions.
