manualfeed
/manualfeed boolean def
in statusdict indicates if a manual feed source has been selected. The boolean
value can be:
true
prints from a manual feed source (default)
false
prints from an automatic feed source
This boolean key can be redefined to affect manual feed for the current job.
If the value of the manualfeed operator or the ManualFeed page device
true
parameter is when showpage or copypage is executed, the page is fed
manually. If both have a value of
executed, the page is fed from an automatic source. These two values are
independent of each other.
Note: If manualfeed is redefined between printing the front and back page of
a duplexed page, the information for the front and back pages is printed on
the same page.
