29 This struct contains (or should contain) all the parameters required for
30 printing a buffer. Some work still needs to be done on this struct and
31 printing handling in general to make it nice and full-featured.
32 The main things I'd like to add now is the ability to print a read-only
33 document with different orientation, papersize or single/duplex state
34 than the document's settings. ARRae 20000423

50 /// We allow printing of even pages in a range and so on.
60 WhichPages which_pages;
61 /** Print a page range. Both from_page and to_page used to be strings
62 because they're actually easier to work with that way. I've
63 switched to_page to be an int. However, from_page will remain a
64 string because I want the from_page field to be able to be used as
65 a page range "1,3-5" and so on.
66 I've modified the invariant test to match. ARRae 20000518
