Label printer and method using a memory frame buffer smaller in size than the label size

Claim 2

A label printing method comprising the steps of: dividing a label into a plurality of areas when a label size is larger than a memory size of a frame buffer on which information to be printed is drawn; sequentially designating drawing enable fields in said frame buffer; and drawing, in units of the divided areas, the information to the designated drawing field included in each of the divided areas so as to print the information on one label.

Claim 3

A label printer comprising: a frame buffer on which information to be printed on a label is drawn, and which has a predetermined storage size; means for dividing said label into a plurality of areas; and means for drawing a drawing field, included in any of said divided areas and including the information to be printed, on a drawing enable area of said frame buffer, so that the information to be printed drawn on said drawing enable area is printed on said label.

Claim 4

A label printer comprising: a frame buffer on which information to be printed on a label is drawn, and which has a predetermined storage size; means for dividing said label into a plurality of areas; and means for drawing a drawing field, included in any of said divided areas and including the information to be printed, on a drawing enable area of said frame buffer, so that the information to be printed drawn on said drawing enable area is printed on said label.

Claim 5

A printer according to claim 2, wherein said dividing means divides said label when a size of said label is larger than the storage size of said frame buffer and a size of said drawing enable area is not more than the storage size of said frame buffer.

Claim 6

A label printer comprising: a frame buffer on which information to be printed on a label is drawn, and which has a predetermined storage size; means for, when a size of said label is larger than the storage size of said frame buffer, dividing said label into a plurality of areas; and means for drawing a drawing field, included in any of said divided areas and including the information to be printed, on a drawing enable area of said frame buffer, so that the information to be printed drawn on said drawing enable area is printed on said label, a size of said drawing enable area being not more than the storage size of said frame buffer.

Claim 7

A label printer comprising: a frame buffer on which information to be printed on a label is drawn, and which has a predetermined storage size; means for, when a size of said label is larger than the storage size of said frame buffer, dividing said label into a plurality of areas; and means for drawing a drawing field, included in any of said divided areas and including the information to be printed, on a drawing enable area of said frame buffer, so that the information to be printed drawn on said drawing enable area is printed on said label, a size of said drawing enable area being not more than the storage size of said frame buffer.

Claim 8

A printer according to claim 4, further comprising: means for drawing on the drawing enable area the drawing field contained in one of the divided areas of said label; and means for drawing on the drawing enable area the drawing field contained in another one of the divided areas of said label.

Claim 9

A printer according to claim 4, wherein said frame buffer includes a first drawing enable area and a second drawing enable area each serving as the drawing enable area, and a size of each of said first and second drawing enable areas is substantially half the storage size of said frame buffer.

Claim 10

A printer according to claim 6, further comprising means for drawing information to be printed next on said second drawing enable area while printing on said label the information to be printed drawn on said first drawing enable area.

Claim 11

A printer according to claim 7, further comprising means for clearing a content of said first drawing enable area and then drawing the information to be printed next on said first drawing enable area while printing on said label the information to be printed drawn on said second drawing enable area.

Claim 12

A printer according to claim 4, further comprising detection means for detecting which divided area includes the drawing field.

Claim 13

A printer according to claim 9, wherein the drawing field has substantially a rectangular shape, and said detection means includes means for obtaining coordinates of corners of the drawing field on said label, and detects which divided area includes the drawing field on the basis of the coordinates of the obtained corners.

Claim 14

A printer according to claim 10, wherein the information to be printed includes characters.

Claim 15

A printer according to claim 10, wherein the information to be printed includes bar codes.

Claim 16

A printer according to claim 10, wherein the information to be printed includes a variable character string.
