Abstract
A hand-held and self contained electronic printing apparatus for printing indicia on a medium disposed outside the apparatus includes a housing that can be manually positioned adjacent a surface of the medium and manually swept across a printing area on the medium during a printing sequence; a printer disposed in the housing and having a print head with a plurality of print elements such as ink jet nozzles for printing indicia in a selectable pattern of dots on the medium within the printing area; and an electronic control circuit disposed in the housing for controlling the printer to print indicia on the medium during a printing sequence, the control circuit comprising compensation for reducing image distortion based on detecting position of the nozzles during a printing sequence.
Claims43
A hand-held and self contained electronic printing apparatus for printing indicia on a medium disposed outside the apparatus, comprising:
- a housing that can be manually positioned adjacent a surface of the medium and manually swept across a printing area on the medium during a printing sequence;
- a printer disposed in the housing and having a print head with a plurality of print elements for printing indicia in a selectable pattern of dots on the medium within the printing area;
- and electronic control means disposed in the housing for controlling the printer to print indicia on the medium during a printing sequence, said control means comprising compensation means for reducing printed indicia distortion caused by movement of said print head along a non-linear path during a printing sequence.
A hand-held and self contained electronic printing apparatus for printing indicia on a medium disposed outside the apparatus, comprising:
- a housing that can be manually positioned adjacent a surface of the medium and manually swept across a printing area on the medium during a printing sequence;
- a printer disposed in the housing and having a print head with a plurality of print elements for printing indicia in a selectable pattern of dots on the medium within a printing area;
- and electronic control means disposed in the housing for controlling the printer to print indicia on the medium during a printing sequence, said control means comprising compensation means for reducing printed indicia distortion caused by a pivoting movement of the print head about an axis during a printing sequence.
Method for printing indicia on a medium disposed outside the printing apparatus, using a hand-held electronic printing apparatus self-contained within a housing, comprising the steps of:
- positioning the housing adjacent a surface of the medium and manually sweeping the apparatus across a printing area on the medium during a printing sequence;
- printing indicia as a selectable pattern of dots on the medium within the printing area, using a print head having a plurality of printing elements, as the apparatus is swept across the printing area;
- and
- compensating for printed indicia distortion caused by a pivoting movement of the print head about an axis during a printing sequence.
