Chapter 4 Application Development Information Notes on Printing Barcodes and Two-dimensional Symbols • The user must set the quiet zone, depending on the barcode standards. • When printing PDF417 (two-dimensional symbols), the following are recommended: Module height: 3 to 5 times the module width Vertical size of the symbol: approximately 5 mm {0.20"} or more • The recognition rate of ladder barcodes and two-dimensional symbols may vary depending on widths of the modules, print density, environmental temperature, type of paper, and characteristics of the reader.
Therefore, the user must check the recognition rate before setting the use conditions so that the restrictions of the reader are satisfied. • Reading quality of barcodes and two-dimensional symbols in graphics multiple tone printing is not guaranteed. • When printing ladder barcodes or two-dimensional symbols with graphics printing, set the print speed to speed level 2. 50
