Method of printing with height adjustable print head

摘要

A method of printing on a mixed sequence of media sheets uses a printer with a print head that is adjustable in height relative to a print surface that supports the media sheets. The media sheets differ in their specifications that define an admissible range for the height of the print head. The method includes the steps of retrieving admissible height ranges for a plurality of media sheets that are scheduled for printing, searching for a height value that is contained in the admissible range of all scheduled sheets, if such a height value is found, adjusting the print head to that height value, and if such height value is not found, proceeding to a problem handling routine.

1. A method of printing on a mixed sequence of media sheets, using a printer with a print head that is adjustable in height relative to a print surface that supports the media sheets, wherein each of the media sheets have different specifications for an admissible height range for the print head relative to the print surface, said method comprising the steps of:
retrieving admissible height ranges for a plurality of media sheets that are scheduled for printing; searching for a height value that is contained in the admissible range of all scheduled media sheets; and if the height value is found, adjusting the print head to the height value; if the height value is not found, proceeding to a problem handling routine, wherein the problem handling routing comprises the steps of:
identifying a media type for at least one of the scheduled media sheets that does not overlap with the admissible ranges for the other scheduled sheets;selecting, from a set of predefined media types, another media type that has an admissible range that does overlap with the admissible ranges of the other scheduled media sheets; andproposing to a user of the printer to replace the identified media type by said another media type.
