I intended to write a detailed review of the Epson Stylus Photo R1800 Printer, but I don't foresee getting the time to properly complete it in the near future. I do want to answer the "Which printer are you using?" question and for that reason feel compelled to keep the page live.
I will leave you with a short summary of my experience with the R1800 ...
This is not your local-superstore-cheap-inkjet-printer. It is heavy (25.8 lbs) and somewhat large - but it is a somewhat-wide format workhorse that rather-quietly produces excellent lab-quality prints with a very long 100-200 year rated life. Eight separate ink cartridges (Cyan, Magenta, Yellow, Red, Blue, Black (matte/gloss), Gloss Optimizer) are a cost-effective design as you are not throwing away unused ink.
I am using Epson's Premium Paper for photo printing. Epson's paper costs less than some other printer manufacturer's paper - be sure to figure paper cost into your long term investment. The Epson Stylus Photo R1800 Printer will print on paper sizes up to 13"x 44" (requires roll paper) and prints on CDs/DVDs as well.
While photo printing output is excellent, business printing (letters, ...) output from the Epson Stylus Photo R1800 Printer is only OK - certainly not fast. Aside from that, I don't have any complaints. I have had prints hanging unprotected since I bought the printer and notice no sign of fading (even with the sun shining directly on them at times of the day/year).
I would buy this printer again.
