There is no savings printing with the 9000 over taking photos to a lab.
The only reason to use it is convenience and if you want to control the output of your work.
The 9000 gives better results than my local labs. If those reasons do not justify the cost of the ink, take your stuff to a lab and avoid the stress.
On small prints it will cost you more to use the 9000 than the labs.
Large prints it balances out somewhat.
AND; Stop printing text, it is an incredible waste of money.
Well, I got my Pro-10 because I wanted to print stuff at home, and I picked it up with a rebate, so the price was good. I have been printing non-photo items on a laser printer for a long time.
First few prints were pretty rough with an uncalibrated monitor and no additional adjustments. I didn't get what I saw, so that would have been interesting if I outsourced the print.
I was kind of hoping it would be a wash with compared to farming stuff out, but I'm not sure. I do have oodles of paper now...
Who knows, maybe it will come down to getting rid of it, or limit the size to 4 x 6 (maybe 5 x 7) for proofing and farm out bigger prints. My internet connection sucks, so uploading big files is an issue.
A 4 x 6 print is 24 square inches, 8 x 11 is 88 square inches and a 13 x 19 is 247 square inches. I guess the use of ink makes sense in those terms.
