Abstract:
1. An apparatus for printing on a block of pages that are pre-bound by a binding along a binding-edge of each page, the apparatus comprising: (a) an apparatus frame; (b) a block support structure configured to allow deployment of the block in said frame so as to form two adjacent stacks interconnected by the binding, such that at least one of the pages is deployed in a first stack and a remainder of said pages are deployed in a second stack, wherein said block support structure includes two block support tables each associated with a corresponding one of said first stack and said second stack, said two block support tables configured such that a relative height of said block support tables is adjustable so as to maintain co-planar printable top surfaces of said first stack and said second stack, using at least one sensor to align the top surfaces of the stacks; (c) a printing device associated with said frame; (d) a displacement mechanism configured to generate relative movement between said printing device and printable top surfaces of said first stack and said second stack so as to print on top surface of at least one of said first stack and said second stack; and (e) a page turning mechanism associated with said frame, said page turning mechanism configured for redeploying a bound top page of said second stack to said first stack so as to produce a new printable top surface.
