I tried this years ago with a big 11 x 17 inch Epson printer. It turned out to be way too much trouble and expense with the ink and the paper and the time involved. The time was spent in tweaking the image in Photoshop, printing test prints, finally getting it just right and then having the printer start streaking or having a clogged ink nozzle. It was maddening! The special archival inks and paper were very expensive.
Finally, I realized that I could save time and money simply by uploading my images to online printing services such as Vista Print or iprintfromhome or FineArt America and/or many others and printing to order.
Things may have changed in the technology since I tried this, but, it is something to think about.
