Inserting barcodes
 When printing barcodes and 2D codes, be sure to use Epson brand ink cartridges.
 When printing barcodes and 2D codes on discs that are not EPSON specified CD/DVDs,
check whether the printed barcodes or 2D codes can be read correctly by a scanner.
 Do not place barcodes and 2D codes where they overlap with other print data, or
where they extend out of the print area.
 Barcodes and 2D codes use the ratio of black to white to indicate information. If ink
penetration results in a deterioration in the ratio of black to white, barcodes and 2D
codes may not be able to be read correctly. Check whether the printed barcodes and
2D codes can be read correctly by a scanner.
 If a barcode printed with bidirectional printing cannot be read correctly, align the print
head (see page 136 in this guide) and then print the barcode, or print the barcode
with unidirectional printing.
