Another Great Epson Printer
Style: WF-3823
This was a great price for a printer that has shown itself to be good print speed and print quality. I have owned Epson printers for years, and this works wonderfully for both home use and small business use. The paper capacity is good, and the wireless connectivity is fine--no problems with that. The weight is good--not super lightweight, but certainly not too heavy as it can be carried and moved with ease. Overall it's great. I have not used the fax function, but all the other functions work fine.

Toss this printer away
Style: WF-3823
Less than a year old and it will not accept Espon print cartridges. I have googled and done everything possible to reboot the printer, but nothing is working

Huge Step Backwards
Style: WF-3823
Purchased this after my WF-3540 finally died. This is a disappointing step backwards in capability for the price. Printing is at best "fine". Getting good color matching / saturation has been a challenge but otherwise acceptable for general things like labels. Despite the confusing documentation (at the time of purchase), this does not do double-sided scanning. This makes using the ADF for multi-sided documents basically pointless. This will be my last Epson. UPDATE - Months have passed and I'm moving it from 2 to 1 star. The ink cartridges run out quickly and are expensive to replace. The ADF jams constantly on scan jobs. The paper pull from the main cassette pulls multiple pages at a time. On top of all that, when using this with a WiFi connection to your network only, the amount of times that it losses connectivity but thinks it is still connected is constant, and/or assigns itself a local IP address instead of getting one from DHCP results in having to cycle power to get it back working. Trash printer.

Happy with my printer!
Style: WF-3823
great buy im super happy with it, i had a HP business printer for about 5 years and I was unhappy with the cost of my $500 ink. So i decided to just buy another printer with a lower cost of ink. I have the same outcome in the printing, great quality, accurate and bright colors. I was able to print business cards and Sticker labels but you can only add 1 sheet to the printer while printing cardstock or labels or it'll jam. But honestly it doesnt matter to me im just happy i dont have to pay so much for ink now. The sheets take a few seconds to print but this is fine for anyone who doesnt need to rush multiple copies. the sheets do shoot out with force when done printing so the sheets do often fall on the floor but if your sitting near you can prevent it. I am able to print wirelessly from both my laptop and iphone!
