/*
* This routine processes all pages in the 'two-sided' mode.
* Reverse is true for LaserJet+, but false for LaserJet II.
*
* If reverse is true, all even pages are output first in reverse order,
* then the odd pages are output in reverse order.
*
* Example:
* First even pages are output: 6 4 2 (2 on top, printed side upwards).
* Then you turn the stack of paper (6 on top, printed side downwards) and
* feed in 6 4 2, and 5 3 1 are printed on the other side.
* 1 is now on top of the stack, printed side upwards.
*
* If reverse is false, all odd pages are output first in normal order,
* then the even pages are output in reverse order.
*
* Example:
* First odd pages are output: 1 3 5 (5 on top of stack, printed side
* downwards). Then you take the stack of paper and
* feed in 5 3 1 (5 on top, printed side downwards), and 6 4 2 are printed on
* the other side. 1 is now on top of the stack, printed side upwards.
