The best printer for your business would be the one that fits in your budget and the one that will suit your business the most.
I'm not being a smarta$$, with these comments. You are the one that should know the best.
Do you have work lined up to have printer busy enough? How often will you print. 1-2 times a week, or will you have steady everyday work.
I am a small shop, print a few prints a week. Used to have Mutoh Falcon that drove me crazy. Not saying that Mutoh is bad, but having to print something every day to make sure printheads will not clog was not fun.
Even with that, I had issue with printheads every few months. That is an older model, new ones should be a bit better as far as the printheds.
Right now, I have HP L25500, which I bought used about 2 years ago. Few small hitches since I bought it, few user-replacable printheads were changed and that was about it when it comes to the problems. I still print a few prints a week, but at least I do not have to worry about the clogged printheads any more.
Again, if you feel that you can feed a solvent printer enough, that might be something for you. If not, your best bet would be a latex printer.
Good luck
