There are Chinese and Japanese printer companies you can check.
I personally advice one of the approved printer production companies such mimaki, roland and mutoh.
There is a very interesting tip about print heads. You MUST keep in mind about printhead replacement.
Mostly; Mimaki, Roland and Mutoh were using DX5 and DX7 printheads which are produced by Epson which is itself a printer manufacturer as well.
As time passes, the deals between companies and Epson are over (or something) and Epson encourages us to buy their own printers.
Whatever the reason is, the result is Mimaki releases printers with different printhead manufacturers such as ts5000 (Ricoh printhead) and ts300 (Panasonic printhead).
Other companies (including Chinese printer manufacturers) will probably switch from Epson printhead to another brand.
What I think is, I don't know what to do. It is like a gamble to choose the printer+printhead combination.
I personally know only Epson DX5 and DX7 printheads. For that reason, I would go with DX7.
