print-4x5 revision 1 produces one 4 × 5 inch print for every quantity.
The paper choices are
lustre (default), pearl, and deep-matte. Read the
matching unit_costs combination and its pricing_status; a null PPU is
unknown, never a zero-dollar print.
rotation_policy: "allowed": it may be
portrait 4:5 or landscape 5:4. WHCC enables its provider placement flag
