Almost everywhere the driver has an option also set on the panel, the driver controls. The one situation I'm aware of that violates this rule of thumb is the Epson 9900's platen gap. Newer (year+ ago) firmware gives the panel a platen gap setting of "widest" that still isn't in the Windows v6.73 (USA) driver. It's max platen gap setting is "wider". If the panel's platen gap setting is set to "widest", what is selected in the driver for platen gap doesn't matter.
