Considering ink prices/paper/printer, it is likely cheaper to go with a pro lab to print stuff and have it mailed to you ^^

I need to be printing 'on the spot' so I really need a printer and paper and ink and all

Already gave you the answer.

yes you did!!!
I my eyes had stopped at the printer, I was not yet ready to look at the paper options haha!!!
I haven't seen your paper here though... I seem to have the choice only between Epson, Ilford and Canon... will look more into it

My printer also has an "ink mod" called the cobra system. You can check it out here: http://www.cobraink.com/CIS/Videos/1400%20kit/start%20video.html

I don't personally have it yet, but my friend does and it saves him a TON of ink.

I'm reading but not sure I understand it to the fullest..
Is it only for Epson?

That kit is specifically for the epson 1400.

I think they have a couple other kits for other epson printers too.

This is for one of them.... I would have to call them... with custom fees, I wonder if it would be better to buy the printer here, and order only the ink system and install it myself... install it myself... why am I scared just by the thought of it???

Marie if you want my honest opinion then buy a nice photo printer and don't print at the shows, there can be so many issues. Not only could a million things go wrong, let says if you have computer issues or printing issues. Something could potentially get damaged, and other then this it will just be a hassle all around. I would take photos and print them at home so you can do quality checks and insure everything is how you want it before clients get it.
