Page Sequential Printing may be used when it is inconvenient for the application to implement Page on Demand printing. In Page Sequential Printing, the application outputs each page of the document in order. Page Sequential printing is done by using the with-page macro, with each invocation of with-page contributing a new page to the document.
Note: with-page does not work on Cocoa.
