I do too. I've invested in my own printer as well.
Make sure you buy one that uses pigment inks - not dye inks.
There are a few Epson models, and many artists use these. They're not the only brand though, so do your research.
When starting out, you might want to find a local print shop that specialises in archival printing, and use their services.
That way you can test out your products on the market before having to make a big investment, as the pigment ink printers can be very $$
good luck!
