In order to print barcodes properly, the bar width of the barcode in the printed data must be corrected. • If you are using the printer driver, select the [General] tab, click [Advanced], select the check box for [Bar Width Adjust- ment], and set it to an appropriate level.

However, the printer driver's bar width adjustment only works when using the printer driver's barcode font, and not in other cases. U "Printing Barcodes" on page 108 • If you are using an application that generates barcodes, cor- rect the bar width in that application. For instructions on how to set it in the application, refer to the application manual. The ink profile or black ink ratio setting needs to be changed. Depending on the paper, the ink ejection amount may need to be adjusted to ensure barcode print quality.

If you are using the printer driver, select the [General] tab, click [Advanced], select the check box for [Ink Profile] or [Ratio of Black to Composite], and set it to an appropriate level. Contact the distributor from whom you purchased the printer for the appropriate level for each paper.
