19. Choose Printer Features to specify printer-specific options. Specify settings for
each selection in the Feature Sets list.
These print options are specific to your machine. You must choose each Feature Set
to see all the options. These options override settings in the machine Printer Setup
but can be changed from Command WorkStation.
If you choose Printer's default, the job prints according to the settings specified in
Setup.
For more information about these options and overrides, see Print Options manual.
Some print options that are selectable from an application are similar to the print
options that are specific to your machine. In these cases, use the print options specific
to your machine that appear in the Printer Features menu. The application may not
set up the file properly for printing on your machine, resulting in unexpected finishing,
printing errors and longer processing time.
If you select an invalid setting or combination of settings when printing a document,
no error message appears. For example, you may be able to select duplex printing
on transparency media. Invalid settings and combinations are ignored by the
machine.
20. Click Print.
