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

According to one example, there is provided a method of duplex printing. The method comprises printing recto pages and associated recto checkmarks on a first side of a web and printing verso pages and associated verso checkmarks on a second side of a web, the length of each successively printed recto and verso checkmark varying in accordance with a respective recto and verso checkmark length sequence, determining the length of successive printed verso and recto checkmarks and determining their sequence position in the appropriate checkmark length sequence, and determining whether a print error has occurred based on the determined recto and verso checkmark sequence positions.

Duplex printing

Method and system for displaying information on one or more aircraft flights, where at least one flight is determined to have at least one atypical flight phase according to specified criteria. A flight parameter trace for an atypical phase is displayed and compared graphically with a group of traces, for the corresponding flight phase and corresponding flight parameter, for flights that do not manifest atypicality in that phase.

Information display system for atypical flight phase

Method and system for analyzing aircraft data, including multiple selected flight parameters for a selected phase of a selected flight, and for determining when the selected phase of the selected flight is atypical, when compared with corresponding data for the same phase for other similar flights. A flight signature is computed using continuous-valued and discrete-valued flight parameters for the selected flight parameters and is optionally compared with a statistical distribution of other observed flight signatures, yielding atypicality scores for the same phase for other similar flights. A cluster analysis is optionally applied to the flight signatures to define an optimal collection of clusters. A level of atypicality for a selected flight is estimated, based upon an index associated with the cluster analysis.
