A dedicated photo printer is an inkjet with paper size restricted to 6x4 thats all- the printed engine in say an Epson model is probably the same or very close to the full size R series.
It is the said that Dye Sub is the best repro.
but you are once more retricted to size - 6x4 unless you opt for one of the rarer Olympus or other models
Then you may have a supplies issue.
I believe click here do a range of Dyesubs
