Abstract: In a printer, a controller controls a printing portion to execute a sample print to print on a sheet a plurality of barcodes. Each of the plurality of barcodes is represented by a received barcode data and printed in a different printing condition. The controller controls a reading portion to read the plurality of barcodes printed on the sheet in the sample print process to obtain a plurality of sets of scan data corresponding to respective ones of the plurality of barcodes. The controller performs a quality determination process to determine qualities of the plurality of printed barcodes based on the respective ones of the plurality of sets of scan data, and a printing condition setting process to set a printing condition based on the qualities determined in the quality determination process. The set printing condition is to be used to print a barcode by the printing portion.
