5745658 A abstract a printer processor in which accuracy of a printed image is essential the printer processor receives exact pixel characteristics from a target printer and instructs the target printer to exactly reproduce the desired image after eliminating any distortions introduced by scaling or rotational factors application_number US 55842195 A description referring now to fig1 a 1d fig1 a illustrates the bitmap for a particular two dimensional code and fig1 b illustrates how that code should appear when printed as shown the bitmap in fig1 a consists of a plurality of 3 u00d7 3 arrays where an array of all 34 1 34 bits results in a black square being printed while an array of all 34 0 34 bits results in a white square i e no printing in this area in contrast fig1 c illustrates a bitmap after scaling by application software located in the cpu or in the printer note how the bitmap has been distorted which results in the printed image shown in fig1 d these distortions can render the printer image unreadable by a machine which is the problem solved by the instant invention fig2 shows a computer based system 100 for printing pixel registered bitmap images which includes a computer 140 application software 150 on the computer 140 image generation software 160 on the computer 140 print driver software 170 on the computer 140 and a printer 180 a user provides data for encoding 110 to be encoded into a bitmap image via the image generation software 160 other user data 120 may be provided in combination with the data for encoding 110.
