bit 3 IPDS print-side reversal
If enabled, the simplex pages of IPDS jobs will be printed on the front side
because of printing on the back side of the page. This might reduce
printing speed.

bit 1 Multiple copies if a paper size or type
mismatch occurs
If a paper size or type mismatch occurs during the printing of multiple
copies, only a single copy is output by default. Using this BitSwitch, the
device can be configured to print all copies even if a paper mismatch
occurs.
bit 2 Prevent SDK applications from altering
the contents of a job.
If this BitSwitch is enabled, SDK applications will not be able to alter print
data. This is achieved by preventing SDK applications from accessing a
module called the "GPS Filter".
Note: The main purpose of this BitSwitch is for troubleshooting the effects
of SDK applications on data.
