A deposition module within a web press for inhibiting media deformation may include a fluid deposition device located on a side of a media, and a processing device to control the fluid deposition device to selectively apply a wetting agent to the media. The deposition of the wetting agent may be based on the location of content printed on the media as defined by print data.

A photo printing device includes a microprocessor, operable to receive photo printing data, a printer, configured to print photographs from the photo printing data, an order sorter, having a plurality of moveable bins for receiving prints from the printer, and means for conveying information to a user related to operation of the order sorter.

The present invention is embodied in a system and method for locally controlling the thickness of a flexible nozzle member of a printhead portion of an inkjet printer. The printing system of the present invention includes a printhead assembly and an ink supply for printing ink on print media. The printhead assembly includes a printhead body, ink channels, a semiconductor wafer, a nozzle member and a barrier layer located between the wafer and nozzle member. The nozzle member has plural nozzles coupled to respective ink channels and is secured at a predefined location to the printhead body with a suitable adhesive layer. The flexible member has a mechanical feature defining local thickness variations of the flexible nozzle member. The mechanical feature can be defined in the flexible nozzle member as extending in a range in close proximity to the ink channel and the adhesive. The mechanical feature reduces the stiffness of the flexible nozzle member near the ink channel or near the adhesive for reducing the stress transmitted to an outside portion of the barrier layer. Thus, the present invention reduces trajectory errors of ejected ink droplets from the nozzles.
