Both print modes offer advantages depending on the type of image being printed.
Unidirectional Printing
Unidirectional printing is recommended for images with fine lines or thin text. Since printing is performed in only one direction, these elements appear sharper and more precise.
Bidirectional Printing
Bidirectional printing is suitable for most images and provides faster printing. It delivers excellent results for graphics that do not contain extremely fine details or delicate text.
