This machine that you mention is a wide-format "desktop", that uses dye-based inks. Not what we think you would be looking for.
First you are looking at plotters. Now you are jumping from a plotter to a printer......????? Okay Lucy, 'splain something to us. What are you trying to accomplish? What is it that you want to be able to produce? Lastly, do you have any resources to try and pull any of this off? The reason for the last question is that you need three main components: 1. Equipment 2. Software 3. Minimal supplies.
Those three questions are important because there are many different directions that a person can go in the
sign business. Many people buy lots of equipment that either ends up being junk from the get-go, or something that is just utterly useless.
