Abstract: A method of image forming comprises the steps of: converting image data into coded data with a code string using a coding key; forming a small pattern string on a sheet of printing paper by printing small patterns, each small pattern corresponding to a code constructing the coded data; recording a coding key or data corresponding to the coding key on a recording medium combined with the printing paper; advising a user to input a decoding key; reading out recorded data from the recording medium; determining whether the decoding key corresponds with the recorded data; scanning the small pattern string recorded on the printing paper when the decoding key corresponds with the recoded data; converting the small pattern string scanned from the printing paper into the code string; decoding the code string into the original image data using the decoding key; and printing an image on a sheet of printing paper based on the image data.

Abstract: A tape printing apparatus, comprising a port for connecting to external apparatus; a first memory for storing label data defining at least one label; and a second memory comprising program information.

Abstract: A tape printing apparatus of the invention includes a character size type storage unit which stores a plurality of types of character sizes; a printable area information storage unit which stores printable area information in a width direction of tape in which a character string is printed; a character size determination unit which determines the character size of each line of an input character string from the character size types based on the number of lines of the input character string and the printable area information of the tape; a character size change instruction operating unit which captures a change instruction of a user for the character size of a line which is specified by the user in the character size of each line determined by the character size determination unit; a character size change process unit which changes the character size of the specified line to a different size in the character size types when the character size change instruction operating unit captures the change instruction of

Abstract: In a rotary press intended to perform the synchronous control of driving means with high precision, quickly stabilize rotation, and reduce spoilage caused by phase shifts, comprising a plurality of printing mechanisms in which driving means M rotate N turns while plate cylinders P rotate one turn, so that printing images can be printed on a paper web sequentially passing through each printing mechanism in such a manner that the printing images are matched with a predetermined reference, in which a control section 3 replaces the rotational phase of the plate cylinder with the rotational phase of the driving means M corresponding to that rotational phase so as to match the printing images with a predetermined reference, converts a shift between the rotational phase of the driving means M for matching and the rotational phase of the driving means M in a normal state into the number of outputs of the first pulse signals, set it as a correction value, and obtains a virtual feedback value by shifting the rotational

Abstract: A controlling method and apparatus for a printer which effects image overlay printing are disclosed. The controlling apparatus comprises an image overlay data storage section, an image overlay data extraction starting position calculating section, and an image overlay controlling section. An extraction starting position of image overlay basic data stored in the image overlay data storage section is normally calculated by the image overlay data extraction starting position calculating section. Consequently, even if image overlay printing is effected over a plurality of print lines, image overlay patterns are not displaced from each other between each adjacent print lines, and a pattern continuous in the upward and downward directions can be obtained.

Abstract: A replaceable font module for a printer includes an interrogable storage containing information representing graphic patterns and is connected to cooperate with a printer upon insertion within a corresponding receptacle. The module and receptacle are configured to allow insertion without intense operator attention by virtue of a camming surface on the module that cooperates with a hook-like latch of the receptacle to provide an undulating but positive latching motion in response to a simple operator insertion motion. As a part of the latching motion, a wiping action to assure a high quality contact with conductor pads on the module that provide a transfer point for the communication path to the storage.
