Abstract

A printing apparatus includes a feed cassette detachably loaded in a main body of the printing apparatus for containing cut sheets, a sheet feeder unit for feeding a cut sheet contained in the feed cassette to the main body of printing apparatus, a printing unit for printing on the cut sheet feed by the sheet feeder unit, a bar code provided on the feed cassette or the cut sheet contained in the feed cassette for representing various information about the cut sheet, a bar code reader for reading the bar code, and an electronic control apparatus for controlling the sheet feeder unit and the printing unit. The bar code reader is provided on the main body of the printing apparatus at which the bar code reader is able to read the bar code when the feed cassette is loaded in the main body of the printing apparatus. The electronic control apparatus controls the sheet feeder unit and the printing unit based on the bar code read by the bar code reader.
