Total Claims: 9
Claim 1
Independent Claim
134 words
A printer apparatus comprising: means for providing print data; means for dividing said print data into a plurality of child data; a print buffer having a first area and a second area, each of said first and second area having a memory capacity equal to or larger than one of said child data; control means for expanding one of said child data to said first area, assigning said first area as a printing area and said second area as a drawing area after completing the expansion of said one child data, and expanding another one of said child data to said drawing area while the print data of said child data is output from said printing area; and means for printing the print data output from said printing area on a given print media.
Claim 2
Dependent Claim
134 words
A printer apparatus comprising: means for providing print data; means for dividing said print data into a plurality of child data; a print buffer having a first area and a second area, each of said first and second area having a memory capacity equal to or larger than one of said child data; control means for expanding one of said child data to said first area, assigning said first area as a printing area and said second area as a drawing area after completing the expansion of said one child data, and expanding another one of said child data to said drawing area while the print data of said child data is output from said printing area; and means for printing the print data output from said printing area on a given print media.
Claim 3
Dependent Claim
76 words
A printer apparatus according to claim 1, wherein when one of said child data is printed, said control means has a function for assigning said second area as said drawing area while said first area is assigned as said printing area; and when subsequent one of said child data is printed, said control means has a function for assigning said first area as said drawing area while said second area is assigned as said printing area.
Claim 4
Dependent Claim
44 words
A printer apparatus according to claim 1, wherein said print data providing means includes: means for generating original print data; means for generating print format data; and means for combining said original print data with said print format data to provide said print data.
Claim 5
Dependent Claim
47 words
A printer apparatus according to claim 3, wherein said given print media includes a label, and said format data includes: data indicating a total length of said label; data indicating the number of said child data; and data indicating a label length of each said child data.
