Roll Feed Printing Extensions: eliminate margins

Some vendor printer drivers support special roll-feed printing modes for eliminating the whitespace around input pages, typically either for banner printing or saving media.

One proposal is the "eliminate-margins (type2 keyword)" Job Template attribute with the following keyword values:

• "all": Eliminate all whitespace at the top and bottom of each page.
• "banner": Eliminate top/bottom whitespace/margins between pages.
• "none": No whitespace/margin elimination.

Another proposal is to define new "imposition-template" values, e.g.:

• "banner": Eliminate top/bottom whitespace/margins between pages
• "compressed": Eliminate top/bottom whitespace/margins for every page.
