: Printer Resolution The Windows 7 printer preferences dialogue box tells me: Print pixels: 1416 x 2152 dots Does this mean that I should always provide an image of 1416 x 2152 pixels to achieve

Note that dye-sub is a VERY different printing process than most ink jet or laser printers (and offset printing, for that matter).

In all those other technologies, the color on the page is created from a mix of 4 different colored dots...CMYK.

Dye-sub, on the other hand, has each individual printer dot its own color. That makes Dye-sub a true continuous tone printer akin to traditional photo paper.

Now, that doesn't help answer your question, but do note that typical CMYK printing concepts/math isn't necessarily going to apply to your dye sub.

What I would do, is trial-and-error to find the optimum mix of quality vs. speed. Since it's a kiosk, there might be some arguments for a slightly decreased image resolution in exchange for a faster printer output.

If by this you mean that your printers specifications state that it is capable of rendering an image this size, no this has nothing to do with the resolution of the image you should provide. It does have a major affect on the image quality your printer is able to produce. Generally, the higher the resolution (dots or pixels wide and high) your printer is rated the finer the possible image quality. That being said, how you work with an image (what size the original, how it was scanned, how it was saved, etc.) all have a major impact on the final image quality. I don't have time go into a lesson on image processing, but general (if you want a high quality print from an inkjet printer) use a dpi rating of at least 300 and save the image at the actual size you want printed out (inches wide and high). This will produce an image resolution as follows. 300 dpi at 4" x 6" = 1200 px x 1800 px. It's about the concentration of pixels per inch. There's a lot more to this, including the settings of the printer itself, but this is all I have time for at the moment.
