All
DTG machines require lots on maintenance & upkeep. If you do not have any
DTG distributor in your country, I would stay away from
DTG for now. It's just too much to learn, and it sounds like you have no experience in the t/shirt business, so this is NOT the machine for you. I would suggest your purchase some used screen print equipment, and learn this business first, especially artwork. If you do not produce your own artwork, then you have to pay to get it done, and that's also extra expense. First learn this business, then look at a
DTG printer later. If you can come to US, then US Screen offers screen-printing classes that will help you get started.
