Turn on bidirectional printing

You can increase output speed by turning on bidirectional printing, which causes the print head to print in both directions. However, the result may be less accurate.

The print direction is saved to the calibration file. You can check whether unidirectional or bidirectional printing is selected on the Media Configuration panel in either Job Editor or Server Manager.

Note: Not all printers support bidirectional printing.

In Server Manager: On the sidebar, click Printers, and select a printer. In the printer's tree view, select a media. On the Media tab, expand the Media Configuration panel.
Under Print direction, clear Switch to unidirectional.
