Abstract: Systems and methods are provided for printer controller, dynamic N-UP print job imaging. An enhanced printer includes features hereof to dynamically adjust parameters of a print job at any point in a print job. In one aspect hereof, the printer configures a print job for an initial set of printing parameters without host system intervention and may reconfigure those parameters during printing of the print job. In another aspect hereof, the adjustments may include adjusting the relative position of any of the N-UP images independent of any other of the N-UP images. Another aspect hereof provides that the formatting of the print job according to printing parameters by the printer occurs after rasterizing the print job into logical page images. Since the formatting is performed after rasterizing, the printing parameters may be changed at any time during printing of the print job.

Abstract: A manually operable hand braking device for such as but not necessarily confined to, a wheel (23) of a wheel chair. The device including a mounting member fixed adjacent the wheel periphery (23a), and a body part (5) mounted for partial rotation about an axis (7) of the mounting member (1) (2) extending transversely of the wheel (23); movement of the body part (5) being effected by a hand grip (26) and lever part (24), extending from the body part (5). The body part (5) being provided with two projecting spaced brake lock parts (21,22) disposed adjacent the wheel periphery (23a) or tire thereon, and arranged so that either of the brake lock parts (21 or 22) are engageable with the wheel periphery (23a) or tire on rotational movement of the body part (5), in one direction or the other, there being an intermediate position permitting freedom of rotation of the wheel (23).
