Methods and systems herein provide for print data compensation for a print head based on a lateral offset of a media relative to the print head. In one embodiment, a print controller of a printer identifies an edge of a media that is parallel to a direction of travel of the media, and determines a lateral offset between the edge of the media and a print head of the printer. The print controller then modifies data for the print head based on the lateral offset to compensate for a lateral motion of the media relative to the print head.

Methods and systems for parallel decoding Run Length Limited (RLL) encoded datastreams is disclosed. In one embodiment, a decoding system includes a parsing system, a first decoder, and a second decoder. The parsing system receives a Run Length Limited (RLL) encoded datastream and identifies a first header and a following header from the datastream. The first header defines a first number of subsequent data blocks and a first RLL encoding of the first number of data blocks. The following header defines a following number of subsequent data blocks and a following RLL encoding of the following number of data blocks. The first decoder is operable to decode the first number of data blocks based on the first encoding and the second decoder is operable to decode the following number of data blocks based on the following encoding in parallel with the first decoder to generate an output.

Methods and systems herein provide for estimating when the print quality of a printer is expected to decrease below a threshold based on a function of change in the print quality of the printer. In one embodiment, a system calculates a plurality of print quality measurements based on pages printed by a printer. The system determines a function of change of the print quality of the printer that is based on changes in the print quality measurements. The system estimates when the print quality of the printer is expected to decrease below a threshold based on the function of change in the print quality of the printer. The system then provides the estimate to a print operator.

Methods and systems for transcoding continuous tone Run Length Limited (RLL) encoded datastreams for including information for identifying halftone screens within the datastream are disclosed. Sequential packets comprising headers and bitmap data are identified within the datastream. Halftone screens associated with bitmap data within the packets are identified and merged into the packets to generate a modified RLL output.
