Printer advice

Hi all,

A few days ago I never even heard of sublimation printing before, but after coming across a few videos I would like to get into it.

Regarding quality, is the most important part the printer? I would like to purchase a printer - looking at Epson 2850 with modification. I understand this will be good enough to print for personal use and hobbies, but if I feel like future proofing, is it good enough to make things to sell?

Ideally, I would like good quality over Aluminum and also over polyester rashguards (MMA training shirts).

Thanks in advance
