Abstract
Abstract A printer control device reading out printing data and format data stored separately from each other for superposing these data to send these data to a printer in a superposed state is disclosed. An identifier indicating a position where printing data is to be superposed on format data is contained in the format data in order to superpose the printing data on the format data with a predetermined positional relation therebetween. As soon as the identifier is read out in course of an operation for reading out the format data, the printing data is read out, and the read-out printing data is combined with the format data.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
116 words
A printer control device for outputting format data and printing data in a superposed state, comprising: a first memory for storing printing data; a second memory for storing format data, said format data containing control information indicative of a position where said printing data is superposed on said format data; first control means for reading out said format data from said second memory to generate a first video signal, and generating a control signal when said control information is read out; second control means responsive to said control signal for reading out said printing data from said first memory to generate a second video signal; and superposing means for outputting said first and second video signals.
Claim 2
Dependent Claim
116 words
A printer control device for outputting format data and printing data in a superposed state, comprising: a first memory for storing printing data; a second memory for storing format data, said format data containing control information indicative of a position where said printing data is superposed on said format data; first control means for reading out said format data from said second memory to generate a first video signal, and generating a control signal when said control information is read out; second control means responsive to said control signal for reading out said printing data from said first memory to generate a second video signal; and superposing means for outputting said first and second video signals.
Claim 3
Dependent Claim
75 words
A printer control device according to claim 1, wherein said printing data is superposed on a plurality of fields included in said format data and said control information contains field specifying information for specifying one of said fields, and wherein said second control means further receives said field specifying information to selectively read out printing data which is to be superposed on said format data at a specified field, thereby generating said second video signal.
Claim 4
Dependent Claim
89 words
A printer control device according to claim 2, wherein said second control means includes a register for holding said field specifying information, a third memory for storing addresses on said first memory where printing data to be superposed on said format data at said fields are stored, in such a manner that said addresses can be read out in accordance with said field specifying information, and third control means for reading out printing data from said first memory in accordance with an address read out of said third memory.
