4-7 PostScript manualfeed /manualfeed boolean def Indicates in statusdict 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 parameter is true when showpage or copypage is executed, the page is fed manually. If both have a value of false when showpage or copypage is 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.
