Hi Mike,
I guess I'd have to agree with Neil and his assessment of the roll paper situation. That's why I usually stock 10, 16, 20, 24, 36 and 44" Luster Paper, and of course various sheet sizes as well. Not all of those sizes for other papers, but I do a lot of printing on Photo Papers for my customers, as opposed to Fine Art Papers. The Fine Art and Canvas sizes are somewhat more restricted. Having a small dealer account I deal with Daymen and get the dealer net, and I buy my Breathing Color Canvas and Iflord Galerie papers from Amplis. Other than Vistek I've never found a distributor in the GTA for Eco Print Shield coatings, so of course I buy from them. For me, convenience is the most important issue to be considered. Time is money and there usually isn't enough of either, and without a 50" D-Roller, ganging prints would be a bit of an issue in my case. However, if you are ever looking for a good layout app for ganging images, the QTR Print Tool is the answer in my opinion. If you are familiar with the QuadTone RIP and its master Roy Harrington you'll certainly know that this little app will do a wonderful job and everything you could want in a layout program. And for $39USD it can't be beat as far as I'm concerned.
Good luck with the 9900 Mike, I'm sure you'll enjoy. One thing I would strongly advise is to get the extended warranty. For the first year and a half my warranty cover the cost of approximately a printer an a half. The third and final warranty period expires in April, but that past year has so far been virtually problem free. It's certainly not inexpensive, but neither is a head replacement, two cleaning stations and and new ink bay. The warranty is a good insurance policy and fortunately I learned that lesson within the first year, which convince me to extend the Epson warranty for as long as possible. After April I'm on my own, but now I know more about the machine and part replacements which will go a long way toward maintaining it for a longer life expectancy. Take care of the 9900 and it will take care of you.
