I'm glad we can totally agree about the paper, even if the ink monitor thing
was a little confusing. Red River paper is also waterproof. I do think you
meant to say with Canon ink and Canon paper when quoting 40¢ per card. Your
other figure of 10¢ per card is about what I came up with using good refill
ink and either RR or OD paper, but I would base that on 4up prints and not
10up business cards.. Actually for me using OD paper it comes out to less
than 3¢ per 4up card since I found a glitch on the OD website a couple of
months ago and was able to buy 1600 sheets at $8.19 per 100. I'll probably
never get a bargain like that again. I know Canadian prices are different
than US, so that may account for the discrepancy in cost figures. FWIW, in
printing business cards, if the original poster uses a layout program like
Microsoft Publisher, 12 cards per sheet can me produced if done in landscape
orientation.
