Select Size Unit.

Representation: CSI s \x20 \x49

Parameter default value: s = 0

SSU is used to establish the unit in which the numeric parameters of certain control functions are expressed. The established unit remains in effect until the next occurrence of SSU in the data stream.

The parameter values are:

  • 0 - CHARACTER - The dimensions of this unit are device-dependent
  • 1 - MILLIMETRE
  • 2 - COMPUTER DECIPOINT - 0,035 28 mm (1/720 of 25,4 mm)
  • 3 - DECIDIDOT - 0,037 59 mm (10/266 mm)
  • 4 - MIL - 0,025 4 mm (1/1 000 of 25,4 mm)
  • 5 - BASIC MEASURING UNIT (BMU) - 0,021 17 mm (1/1 200 of 25,4 mm)
  • 6 - MICROMETRE - 0,001 mm
  • 7 - PIXEL - The smallest increment that can be specified in a device
  • 8 - DECIPOINT - 0,035 14 mm (35/996 mm)
