Set the printer basic units of measurement.
This command is used to set various global units of measurement that the printer can refer to with subsequent commands. Measurements are based on the Imperial system and are in fractions of an inch.
ESC 0x28 0x55 05 00 PU VU HU BU(2)
PU = Page Units expressed in base units
VU = Vertical Units expressed in base units
VU = Horizontal Units expressed in base units
BU = base units (note little endian) expressed in 1/nth of an inch/
ESC 28 55 05 00 04 04 04 A0 05
Subcode 0x55
Bytecount 0x0500 = 0x0005 = 5 dec
PU 0x04 = 4 dec Base units = 1/360th inch/2.77mil/0.07mm
VU 0x04 = 4 dec Base units = 1/360th inch/2.77mil/0.07mm
HU 0x04 = 4 dec Base units = 1/360th inch/2.77mil/0.07mm
BU 0xA0 05 = 0x05A0 = 1440 dec = 1/1440th of an inch/0.694mil/0.0176mm
In this example the vertical and horizontal units are the same representing 360dpi x 360dpi
ESC 0x28 0x43 ESC 0x28 0x63 ESC 0x28 0x63 ESC 0x28 0x53
ESC 0x28 0x76 ESC 0x28 0x56 ESC 0x28 0x2F ESC 0x28 0x5C
There is another variant of this command with a byte count of 1.
Some older commands don't refer to these global measurement units.
