A method of increasing data flow to a printing device includes, with a first raster image processor, converting a document into a first bitmap having a first dot density and representing a black color plane of the document; with a second raster image processor, converting the document into a second bitmap at a second dot density that is a relatively lower dot density than that of the first bitmap, the second bitmap representing other color planes of the document; and transmitting data of the first and second bitmaps to a printing device for printing to a print medium.

Data flow to a printing device

A technique includes in a machine, processing data indicative of a document to be printed by a printer and which may contain magnetic ink character recognition (MICR) characters to determine whether the data indicates any MICR characters. The technique includes comparing a result of the determination to an intent indicated by a job ticket associated with the document; and controlling the printing of the document by the printer, including selectively performing corrective action in response to the comparison.

Controlling printing of a document that may contain MICR characters

Disclosed are various embodiments of various systems that facilitate the printing of documents. In one representative example, one arrangement includes a plurality of raster image processors, a plurality of frame brokers, and a first digital switch facilitating communication between the raster image processors and frame brokers. The arrangement also includes a plurality of printers and a second digital switch facilitating communication between the frame brokers and the printers. A central control system orchestrates a progression of frames of a plurality of documents through the raster image processors and the frame brokers to the printers.
