How to Speed Up Making Your Proxy Cards! 

Thank you, I'm glad you found it helpful. As far as printing settings go I can only really go through the basics like making suring you're selecting the right type of paper you're using in the printer settings and setting it to the highest quality. When you say you're getting varying results do you mean every time you print the same thing or when comparing it to what you see on screen? In terms of detailed advice I can't proclaim to be an expert but I do know that the recommendation is that you set Photoshop (or equivalent) to manage the colour management, making sure to turn colour management off in your printer settings. I have never found that this has done anything but its worth passing on consensus advice. Similarly it is usually suggested that you work with your images in CMYK mode as opposed to RGB when you're playing around with print media, but again in my experience that only serves to flummox Photoshop if and when I need to tweak the levels on the image. I tend to try doing an auto adjustment on the curves (in the adjustments tab of the image in Photoshop) as it generally brightens the image up a bit as I tend to find the colours are a lit bit darker than I was expecting but other than that I use the default settings. If you're asking about ICC or printer profiles or stuff like that then unfortunately I wouldn't be the best to give advice, although perhaps thats a worth subject for more research.
