Abstract
Abstract A form overlay type document printing apparatus includes a format memory (2) for storing form data, a repetition data memory (3) for storing common data to be printed on successive documents, and a variable data buffer (4) for storing data which is unique to such document. A printing pattern generator (7) converts the repetition data and unique data to corresponding printing signals and a form pattern generator (5) generates printing signals for reproducing a selected form. The printing signals corresponding to the form data and the repetition data are combined and repetitively supplied to an output buffer (9) as long as there is no change in the form or the repetition data. The printing signals corresponding to the unique data are also supplied to the output buffer (9). The contents of the output buffer (9) are supplied to a head driver (10) which controls a printing head (11) to generate the desired printed output. In this manner, only the unique data and data arising from a change in the form or the repetition data need be transmitted from a host computer to the printing apparatus.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
188 words
A form overlay type document printing apparatus for receiving form data, repetition data, and variable data from a host computer and for producing a printed output corresponding thereto, characterized by the apparatus comprising: a format memory (2); a repetition data memory (3); a variable data buffer (4) ; input data means (1) for supplying form data, repetition data, and variable data received from the host computer to said format memory (2), said repetition data memory (3), and said variable data buffer (4), respectively, a form pattern generator (5) for generating form printing signals corresponding to said format data stored in said format memory (2); a printing pattern generator (7) for generating repetition printing signals corresponding to said repetition data and variable printing signals corresponding to said variable data; a form pattern buffer (6) for combining said form printing signals and said repetition printing signals to output a selected sequence of combined printing signals for a succession of documents; and an output buffer (9) for combining said combined printing signals with said variable printing signals to produce corresponding print driver signals for each document in said succession of documents.
Claim 2
Dependent Claim
188 words
A form overlay type document printing apparatus for receiving form data, repetition data, and variable data from a host computer and for producing a printed output corresponding thereto, characterized by the apparatus comprising: a format memory (2); a repetition data memory (3); a variable data buffer (4) ; input data means (1) for supplying form data, repetition data, and variable data received from the host computer to said format memory (2), said repetition data memory (3), and said variable data buffer (4), respectively, a form pattern generator (5) for generating form printing signals corresponding to said format data stored in said format memory (2); a printing pattern generator (7) for generating repetition printing signals corresponding to said repetition data and variable printing signals corresponding to said variable data; a form pattern buffer (6) for combining said form printing signals and said repetition printing signals to output a selected sequence of combined printing signals for a succession of documents; and an output buffer (9) for combining said combined printing signals with said variable printing signals to produce corresponding print driver signals for each document in said succession of documents.
