I just did a costing on the basis of actaul photos that I have printed over the last 11 years on ink jet printers. Over $1000 on printers and about $400 in ink.
Note: I have always used a laser for text printing
From this I have probably printed 12 or so photographs and about 200 CD/DVD's (The real reason for an ink jet printer). That works out at around $7 each successful print. However the CD/DVD's have only been printed with my current printer so the cost of these is less tha $1 per print. That means the older printers on which I spent about $1000 on printers and ink for a net 12 photos. Not very economical is it.
