Barcode printing method and barcode printing device

The invention provides a barcode printing method and device. The method includes: a) receiving a printing instruction from external equipment; b) parsing a plurality of printing information streams; c) calculating initial coordinates of a barcode; d) determining a first coordinate range of each row according to printing information of the row, wherein the first coordinate range is a coordinate range which is in the row and other than that of characters; e) using the initial coordinates of the barcode as current coordinates, determining whether the current coordinates are in the first coordinate range and height of the barcode is less than or equal to row height of the row where the barcode is located, if yes, using the current coordinates as printing coordinates of the barcode, and entering a step g), and otherwise, entering a step f); f) adding a predetermined amount to an ordinate or an abscissa in the initial coordinates of the barcode, using new coordinates as the printing coordinates of the barcode, and
