Abstract
Abstract A printer apparatus comprises: a holding circuit to hold a pattern of a character, a figure, or the like in a form such that it can be enlarged or reduced into an arbitrary size; a converter to convert the pattern of the character, figure, or the like which was held in the holding circuit into a printable dot image of an arbitrary size; and a forming circuit to form a reduced dot image of the character, figure, or the like by the converter in accordance with reduction ratios of a character pitch and a line pitch upon reduction printing in the printer emulation mode. With this apparatus, the reduced print image which accurately conforms with the reduction ratios can be obtained.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
113 words
A printer apparatus for printing data prepared for a continuous sheet on a cut sheet, said apparatus comprising: means for storing a pattern of a character represented by non-dot matrix data; means for converting the pattern of the character stored in said storing means into a printable dot image of an arbitrary size so as to enable printing of data prepared for a continuous sheet; and means for controlling said converting means to convert the pattern of the character into a reduced dot image of the character in accordance with reduction ratios of a character pitch and a line pitch upon printing the data prepared for the continuous sheet on the cut sheet.
Claim 2
Dependent Claim
113 words
A printer apparatus for printing data prepared for a continuous sheet on a cut sheet, said apparatus comprising: means for storing a pattern of a character represented by non-dot matrix data; means for converting the pattern of the character stored in said storing means into a printable dot image of an arbitrary size so as to enable printing of data prepared for a continuous sheet; and means for controlling said converting means to convert the pattern of the character into a reduced dot image of the character in accordance with reduction ratios of a character pitch and a line pitch upon printing the data prepared for the continuous sheet on the cut sheet.
Claim 3
Dependent Claim
33 words
A printer apparatus according to claim 1, wherein the pattern of the character in said storing means is outline font data which expresses the outline of the pattern by a coordinate dot train.
Claim 4
Dependent Claim
23 words
A printer apparatus according to claim 1, wherein the size of the dot image can be independently determined in vertical and horizontal directions.
Claim 5
Dependent Claim
34 words
A printer apparatus according to claim 1, further comprising a laser beam printer, wherein said storing means, said converting means and said control means perform their functions in conjunction with a memory work area.
Claim 6
Independent Claim
109 words
A method of printing data prepared for a continuous sheet on a cut sheet, said method comprising the steps of: storing a pattern of a character represented by non-dot matrix data; converting the pattern of the character stored in said storing step into a printable dot image of an arbitrary size so as to enable printing of data prepared for a continuous sheet; and controlling said converting step to convert the pattern of the character into a reduced dot image of the character in accordance with reduction ratios of a character pitch and a line pitch upon printing the data prepared for the continuous sheet on the cut sheet.
Claim 7
Independent Claim
109 words
A method of printing data prepared for a continuous sheet on a cut sheet, said method comprising the steps of: storing a pattern of a character represented by non-dot matrix data; converting the pattern of the character stored in said storing step into a printable dot image of an arbitrary size so as to enable printing of data prepared for a continuous sheet; and controlling said converting step to convert the pattern of the character into a reduced dot image of the character in accordance with reduction ratios of a character pitch and a line pitch upon printing the data prepared for the continuous sheet on the cut sheet.
Claim 8
Dependent Claim
33 words
A method according to claim 5, wherein the pattern of the character stored in said storing step is outline font data which expresses the outline of the pattern by a coordinate dot train.
Claim 9
Dependent Claim
22 words
A method according to claim 5, wherein the size of the dot image can be independently determined in vertical and horizontal directions.
Claim 10
Dependent Claim
26 words
A method according to claim 5, wherein said storing step, said converting step and said control step are performed in conjunction with a memory work area.
