Abstract
Abstract There is disclosed a printing apparatus implemented as a laser printer capable of changing the print format when outputting print data. When the operator changes the print format at the printer, the CPU changes the print data in a text buffer of a built-in RAM according to the changed print format, the data being converted into image data in a dot pattern for storage into an image buffer. The operator then pushes a reprint key, causing the CPU to read the pages of print data stored in the image buffer for outputting to a laser printer engine via a printer engine interface for reprinting. The printing apparatus allows the print format to be changed easily for efficient reprinting of the last print data in the new format without the need for the host computer to supply the same print data again.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
143 words
A printing apparatus, comprising: a memory for storing at least one printout page of print data fed from an external device; printing means for printing at least a first printing of the print data stored in said memory; print format setting means for setting a print format in which the print data stored in said memory is printed; print control means for reading the print data from said memory for printing by said printing means; and print data converting means for modifying the print data to a changed print format if the print format for the print data stored in said memory is changed by said print format setting means, wherein said printing means subsequently prints the modified print data as a second printing such that information content of the first printing and the second printing are identical but a presentation is changed.
Claim 2
Dependent Claim
143 words
A printing apparatus, comprising: a memory for storing at least one printout page of print data fed from an external device; printing means for printing at least a first printing of the print data stored in said memory; print format setting means for setting a print format in which the print data stored in said memory is printed; print control means for reading the print data from said memory for printing by said printing means; and print data converting means for modifying the print data to a changed print format if the print format for the print data stored in said memory is changed by said print format setting means, wherein said printing means subsequently prints the modified print data as a second printing such that information content of the first printing and the second printing are identical but a presentation is changed.
Claim 3
Dependent Claim
34 words
The printing apparatus according to claim 1, wherein said print control means reads the print data for the second printing from said memory independently of the external device for printing by said printing means.
Claim 4
Dependent Claim
50 words
The printing apparatus according to claim 1, wherein said memory has a register for storing the print format set by said print format setting means, said printing apparatus further comprising setting change detecting means for monitoring contents of said register to detect any print format change that may be made.
Claim 5
Dependent Claim
148 words
A printer, comprising: a control processing unit; a control panel; a first memory for storing a control program for the printer; a second memory having plurality of areas for separately storing at least data input from an external source, print format data, and image data for printing developed from the data input and the print format data; a printer interface; and a print engine for printing the image data, wherein said control panel includes a reprint key and at least one format key for establishing and changing the print format data, wherein said control processing unit controls the print engine to print the image data based on original image data as a first printing, said reprint key permitting a second printing of a one of the image data and an altered image data when said at least one format key is used to change the print format data.
Claim 6
Dependent Claim
148 words
A printer, comprising: a control processing unit; a control panel; a first memory for storing a control program for the printer; a second memory having plurality of areas for separately storing at least data input from an external source, print format data, and image data for printing developed from the data input and the print format data; a printer interface; and a print engine for printing the image data, wherein said control panel includes a reprint key and at least one format key for establishing and changing the print format data, wherein said control processing unit controls the print engine to print the image data based on original image data as a first printing, said reprint key permitting a second printing of a one of the image data and an altered image data when said at least one format key is used to change the print format data.
Claim 7
Dependent Claim
30 words
The printer as claimed in claim 4, wherein said at least one format key allows setting of at least one of font, print layout, sheet size, magnification factor and color.
Claim 8
Dependent Claim
17 words
The printer as claimed in claim 4, wherein said second memory stores text data for one page.
Claim 9
Dependent Claim
19 words
The printer as claimed in claim 4, wherein said second memory stores text data for a plurality of pages.
Claim 10
Dependent Claim
133 words
A printing apparatus, comprising: a receiving buffer for storing text data from an external device; a register for storing print format data; a text buffer for storing print data; an image buffer for storing image data as a dot pattern that is developed from the print data; printing means for printing the image data; print format setting means for setting print format data, the set print format data being stored in said register as the print format data; and control means for replacing existing print format data stored in said register based on the print format data set by said print format setting means, wherein said control means adjusts the print data stored in said text buffer using the print format data set by said print format setting means for a subsequent printing.
Claim 11
Dependent Claim
133 words
A printing apparatus, comprising: a receiving buffer for storing text data from an external device; a register for storing print format data; a text buffer for storing print data; an image buffer for storing image data as a dot pattern that is developed from the print data; printing means for printing the image data; print format setting means for setting print format data, the set print format data being stored in said register as the print format data; and control means for replacing existing print format data stored in said register based on the print format data set by said print format setting means, wherein said control means adjusts the print data stored in said text buffer using the print format data set by said print format setting means for a subsequent printing.
Claim 12
Dependent Claim
23 words
