Definitions

• the handheld printer devices By means of the present invention it has been made possible for the handheld printer devices to provide printouts that are adapted to the available printout surface, so that it is possible to ensure that that printout surface is utilised in a desired and/or optional manner, or to ensure that the surface is large enough.
• the position information is x- and y-coordinates . These coordinates may be displayed in a display of the handheld printer device, enabling the user to see the coordinates as he/she moves the handheld printer device over a printout surface .
• the handheld printer device includes sensors 3 for sensing movements of the print head 2, and thus the movements of the handheld printer device, for enabling the ejection of ink drops when required.
• the handheld printer device thus includes means for determining at each moment the position of the handheld printer device in relation to the printout surface, which feature is utilised in the present invention.
• the user may conveniently adjust the size of the desired printout image. He or she just switches the handheld printer device to the "print mode" and selects an appropriate scale for the printout image. Given the size of the printout surface 10, the printout image may for example be printed in a "best fit" scale.
• the bitmap for the printout image may be adjusted to the measured size of the printout surface in any appropriate manner.
• the printout image may be adjusted or scaled in the handheld printer device or in a separate server, where the printout image is stored. The conversion to a bitmap may also be performed in the handheld printer device or in a separate server.
• the software used for scaling the printout image may be any commonly known software, for example an image processing program.
• the resolution of the image may determine the size of the printout image, as may also the capacity of the print head 2. If the print head 2 is able to print 100 dpi (dots per inch) , this may be a limiting factor for the size of the printout image. It is further realised that a printout image may be reformatted into different resolutions enabling different sizes of the printout image.
• This edge detecting means could be used in order to detect when the handheld printer device passes over an edge and thereby initiate the measuring operation.
• the edge detection means When the handheld printer device passes over a second edge, as detected by the edge detection means, the measuring operation is completed.
• a user for example has a commonly used size A4 paper, all he or she has to do is to move the handheld printer device over the paper in one direction, after which the handheld printer device is able to detect that the desired size of the printout surface is A4.
