Pixel-exact driver for EVOLIS Dualys two-side card printer in perl This is experimental support for EVOLIS Dualys 3 printer with black ribbon (K) to provide pixel-exact driver with support for two-side printing. Existing cups driver available at http://www.evolis.com/eng/Drivers-Support/Product-support/Dualys-3 does work, but I haven't been able to make it print duplex on cards, especially when generating front and back pages separatly.
