Description
Select an SSU parameter as follows:
Ps Action
2 Selects decipoints, 1/720 inch.
7 Selects pixels (printer-specific
?1 Selects centipoints, 1/7200 inch
SSU selects decipoints, centipoints, or pixels as the unit for certain
control functions, as noted under the individual commands in this
chapter.
In some cases SSU works with Positioning Unit Mode (PUM) to
determine the unit used. If PUM is reset, characters are used,
regardless of the SSU setting. If PUM is set, decipoints, centipoints,
or pixels are used, based on the SSU setting.
In other cases SSU is used alone, and PUM has no effect.
SSU remains in effect until the printer receives another SSU
command or until reset or power down. SSU only affects sequences
that follow it in the data stream.
Error Handling
Selective parameters other those shown above are ignored.
