<p>Thanks again to everyone for the advice. All told, I may just take the Red River conclusions and call it a day! </p>

<p>Thanks everyone for the lightning fast reply - great information.</p> <p>My "test" was not perfect. I was planning on identical sizes similar subjects, but I realize unless they are identical photos each one takes a different amount of ink. The subjects (graffiti paintings) are similar in color schemes.</p> <p>I didn't hit on my search for similar calculations, but I'll try again.</p> <p>Thanks again!</p>

<p>I have an Epson 3800. I want to experiment on ink and paper costs in advance of a run printing a few particular images. My existing cartridges range from almost empty to almost full. I would like to remove them, install a full set of new cartridges, print them until they run dry (to calculate the cost per print). I would then re-install my existing partially used cartridges.</p> <p>Will I be able to reinstall the old cartridges?</p> <p>Thanks for your help!</p>
