Abstract
In a print system including a host communicating with an inkjet print apparatus, a processor executes an inkjet print driver. The driver manages print job communication to the inkjet print apparatus. The print job includes print data and at least one print control parameter. The inkjet print apparatus includes a controller, an inkjet print source which records the print data onto a media, and a mechanism which adjusts source-to-media spacing. The controller responds to a first parameter of the at least one print control parameter to control setting of the source-to-media spacing by the adjusting mechanism for the print job.
Claims37
A print system, including a host communicating with an inkjet print apparatus, wherein the host comprises a processor which executes an inkjet print driver, the inkjet print driver managing communication of a print job to the inkjet print apparatus, the print job including print data and at least one print control parameter, the inkjet print apparatus comprising a controller, an inkjet print source which records the print data onto a media, and a mechanism which adjusts source-to-media spacing, wherein the controller responds to a first parameter of said at least one print control parameter to control setting of the source-to-media spacing by said adjusting mechanism for the print job.
An inkjet printing apparatus having an adjustable source-to-media spacing, comprising:
- a sensor which senses a media surface within a vicinity of a print zone;
- an inkjet print source which ejects ink onto the media surface within the print zone;
- and
- a controller which adjusts the inkjet print source relative to the media to control source-to-media spacing as a function of the sensed media surface.
An inkjet printing method, comprising sensing a media surface within a vicinity of a print zone;
- adjusting the inkjet print source relative to the media to control source-to-media spacing as a function of the sensed media surface;
- and
- ejecting ink with an inkjet print source onto the media surface.
An inkjet printing apparatus having an adjustable source-to-media spacing, comprising:
- means for sensing a media surface within a vicinity of a print zone;
- means for maintaining a source-to-media spacing generally constant in presence of changes in the sensed media surface;
- and
- inkjet means for ejecting ink onto the media surface within the print zone, wherein the source-to-media spacing is a nearest distance between the ejecting means and the media surface.
