For any of my usual printing I have no concern over the time a print takes, but I'm about to print 100+ greeting cards. These are not for sale, just family use. Between the Canon driver, and Lightroom settings, I have no luck in getting a faster output. Is it even possible? The "custom" option within the driver limits me to the two slower speeds, perhaps because of my paper choice (a matte photo stock) There's also no difference between the original high-res 16 bit psd, and a resized jpg. Not a big deal, but I am curious. Thanks.
