Patent Images
1. A hand-held and hand-operated random movement printing device controlled by at least one processor (4), controlling comprised means to perform their intended tasks, having an ink-jet print-head (2) assembly comprised in a housing (1), further comprising:
- at least one ink container;
a transmitter for transmission of electromagnetic radiation on a print medium;
a receiver for receiving reflected electromagnetic radiation from said print medium;
digital signal processing means providing a digital signal of the inherent information received by reflected radiation;
a memory storing a digitised raster of a code pattern for printing a plurality of marks, each mark being related to a coordinate in an imaginary coordinate system made up of the raster to be printed on said print medium, said memory also storing an image to be printed on the print medium, said image being associated to coordinates in the imaginary coordinate system;
a print-head array disposed to have nozzles for printing a raster of a code pattern, and print nozzles for the image to be printed, printing a part of the pattern through spray dozes from the nozzles and related parts belonging to the image; and
whereby said raster of a code pattern enables the printer to be randomly moved over a print medium still keeping track of the print-head arrays position, and integrates the image to the coordinate system to be coherently printed.

Abstract
A hand-held and/or hand-operated random movement printing device is controlled by at least one processor. The printing device provides a control to determine the position of an ink-jet print head assembly on a print medium. Specifically the assembly prints a pattern that it uses to determine its position.

9. A method for a hand-held and hand-operated random movement printing device controlled by at least one processor (4) controlling comprised means to perform their intended tasks, having an ink-jet print-head (2) assembly comprised in a housing (1), at least one ink container, and a memory storing a digitised raster of a code pattern for printing a plurality of marks, each mark being related to a coordinate in an imaginary coordinate system made up of the raster to be printed on a print medium, and also storing an image to be printed on the print medium, said image being associated to coordinates in the imaginary coordinate system, comprising the steps of:
-
transmitting electromagnetic radiation on a print medium through a comprised transmitter;
receiving reflected electromagnetic radiation from said print medium through a comprised receiver;
providing a digital signal of the inherent information received by reflected radiation by comprised digital signal processing means;
printing, through print nozzles in the print-head array, a part of a raster of a code pattern, and printing related parts of the image;
whereby said raster of a code pattern enables the printer to be randomly moved over a print medium still keeping track of the print-head arrays position, and integrates the image to the coordinate system to be printed in a coherent manner. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
