203, 305 or 609 dpi, and how to choose
Resolution is not a quality contest, it is a function of what is on the label. A standard GS1-128 case label with human readable text is comfortable at 203 dpi. Small 2D codes, fine print, tight artwork or anything a scanner will struggle with at the far end of a warehouse is where 305 or 609 dpi earns its place. Higher resolution slows the print, which is why the label design and the line rate have to be settled together rather than in sequence.
