hobbyist only
Purchased to replace a 15 year old Epson. I still have three weeks to decide to return this so I will edit this review if I decide to do that. PROS: After a few test prints, I love the quality of color, the accuracy of reproduction to what I see on my monitor, and the number of choices for print size and quality. I found, as others complained, that with cheap gloss paper there was puddling of ink. When I switched to my best papers, especially my favorite highest quality matte finish, the results were astounding and I'd do matte for everything. As for ink usage, I made the choice to go with a cartridge printer instead of the newer high-volume inks because I wanted the archival quality. Test the output for your needs, because I found the "draft" setting produced better on gloss paper. CONS: Like so many electronics now, you only get instructions if you download and print them. Second, when the printed photo feeds out, it has been curled and as it feeds into the receiving drawer, wants to drag the wet ink against the body of the machine. You have to be there to watch and push it down with a finger. Cheaper gloss paper in 4x6 size curled up in a little wet roll 1/2" diameter and is not usable AT ALL. The miniature screen on which to select papers is ridiculous. I wish the computer interface let you make the choices on your computer, but it does not.

Defective printer and poor wifi performance
I cannot recommend that anyone buy this printer. At this price, I expected a consistently working and decent quality printer. For initial wireless setup with a Mac, we had to spend 45 minutes on the phone with Epson technical support. That got it working. It worked for a couple of weeks and then the printer would frequently lose its wifi connection even though our internet is high quality cable and very consistent. We'd have to turn this printer off and on repeatedly to re-establish the wifi connection. Then after 6 weeks it stopped working totally. After another 45 minute call with Epson, they said it had a hardware failure and we had to return it to Epson and would receive a refurbished unit. This is less than 2 months after buying a new high priced printer that they are suggesting we accept a refurbished unit. Finally Epson said they'd send a new one. We got the new one and did our customary call to tech support to set it up for wireless with a Mac. It turns out they forgot to send the factory ink cartridges in this replacement printer that are required to do an initial setup. We have the Epson cartridges that are spec'ed for this printer, but they have to be the ones that COME INSIDE the printer for the printer to begin its initial setup. So after another 45 minute call, Epson now says they have to send us new ink cartridges for the printer to even print a single piece of paper - even though we have Epson ink cartridges purchased just for this computer. So after weeks of no printer for our business, we now have to wait for another shipment from Epson. Then we will have the next 45 minute call to set it up.. This painful and costly experience has had way too many headaches - all caused by Epson defects and mistakes. We will not be buying Epson again.

A must have high quality Photo Printer for cheap!
If you’re searching for a high quality printer without breaking the bank , this is the printer for you. I had spent a good amount of time researching various printers and the picture quality they offered . I really spent my time looking this up . I found that the Picture quality on this printer is incredible . If you look at other models that can print 13x19 they cost way more. Now the ink capacity I’m not entirely sure about but I do know the ink can be expensive but it’s a trade off for getting an affordable printer without breaking super high quality pictures . Setup was very straight forward and it makes it essentially easy for anyone to connect to their network to print wired or wireless. You have the ability to print from your phone which is really amazing as well . All around this printer is great and if you’re hesitant you should just pull the trigger because you get quality with this model and affordability .
