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.

Abstract: There is provided a printing apparatus, including: a casing having a discharge opening and a conveyance route; a roller; a driving source; a printing head; a scanner disposed at a downstream side in a discharge direction; and a controller. The controller is configured to, depending on a printing preparation command, detect a leading-end position of a sheet; determine whether a printing surface of the sheet includes an error position that is not suitable for printing; and convey the sheet until the error position reaches the downstream position from the printing head. Then, the controller controls the printing head to execute printing of an image on the sheet.
