I bought a professional printer to print my own photos and T-shirt transfer papers. It does print large sizes but for now I offer 8×10 and 8.5×11. I have some of my best photos listed on my site now and I will be adding more.
Right now it is costing me a small fortune to print but over time the costs will go down. The quality is just as good as zazzle and cafe press. I plan to start another ebay store to offer these prints and T-shirts.
I have two sizes listed, one is an 8×10 with a broad white border so no matting is needed. The other is full 8.5 x 11 to fit in 11×14″ frames with matting. I can print up to 13×19″. This will be great for T-shirts and prints.
