Surprisingly Impressed, but DO NOT subscribe to ReadyPrint
Before we dive in, just a quick shout out for Amazon: Ordered late afternoon 5th Feb 2024. Printer arrived 13:30 7th Feb 2024. That...is pretty amazing. And I didn't have to do anything! Back to the printer: I needed this printer fast because my existing one from the Canon family decided that the absorber pads were *nearly* saturated. I watched Youtube and cleaned them beautifully. No change. Since calling someone out would cost more than the value of the (8 year old) printer, I decided to replace it and silently curse the manufacturer of my old one. The box is quite big and heavy, just saying. Items well packed though and it took several minutes to rid the printer of blue tapes and get it ready...but nothing unusual there. What was disappointing was an absence of printer USB cable. Note that, potential buyers. Luckily, the old Canon one worked so no harm done. I wish the "Get Started" documentation had mentioned that users should get online and start the set up process immediately from there. As it was, I was faced with the (lovely) touch screen telling me to do stuff but waiting for the online to be activated. Confusing. However, once I got my stuff together, the set up was slick and reassuring. Lots of help and "Next" buttons. The only issue came with connecting the wifi. The set up suggests not using the Wifi Wizard. Be careful here, because choosing "Other->Wifiauto" means using the WPA button on your Hub. I nearly freaked out when nothing seemed to be happening but pressing the button appeared to do the trick. The printer is tall, but not a huge footprint. Printing or scanning on normal/standard quality is very fast indeed (good). However, if you choose fast/High Quality especially on scan (say 400 res) this takes a long time (but probably much the same for most scanners) I have subscribed to Readyprint 30pages a month and will try to remember to update this review with what I think of it. The overall look of the printer is great, despite the vertical bulk - the pull-outtable 45 degree menu panel is awesome really like that. Finally, after the set up was complete, I asked my wife to connect & print from her iPad. No problem, print was almost instantaneous from downstairs. Overall, this is a jolly fine printer print. Stay tuned for the update. 18/02/2024 Update 1. The printer: Still very pleased with this printer. Prints on "standard" are very, very quick. I have discovered that you can scan documents through wifi which my previous Canon would not do. Awesome!! Still love the touch menu - I wanted to see how much ink was left after a few bw/colour prints - amazingly only a tiny amount user (I was given the impression that ink tanks shipped with new printers were basically only sufficient to set-up and a few sample prints: Not True. The scanner has a preview which allows you to tweak books whose pages you are trying to scan. 2. Epson ReadyPrint. I have already received a replacement set of cartridges even though I do not need them (see above). I have signed up for "30 pages per month" @ £1.99 pm. Not sure how accurate my 30 pages is, but we'll see. I am expecting either to be inundated with new cartridges or not receive any more for months even though I may need them. Let's see how this pans out. 24/06/2024 Printer still as good as reported. Be careful with Readyprint. My old credit card had to be cancelled and replaced by a new one. I neglected to update the new payment method on my ReadyPrint account. So when the electricians shut off my supply for a few hours to do repairs and it came on the printer would not print. I thought I just had to reconnect. Simple. But 30 minutes pfaffing around it was still not printing. Then I looked very carefully at the error message and it mentioned account issue. Logged in and found the payment issue detailed above. Removed the old card and added the new. Once new card verified, a couple of reconnects were necessary before my print would emerge. Phew. 21/01/2025 I knew this was coming. The Readyprint subscription was too good to be true. So the 30 pages a month @ £2.99pm has now escalated to £11.99 pm but we definitely do NOT print 90 pages in a month. Luckily, I am the sort of annoying person who checks all subscriptions for value. I have now cancelled the subscription but not before ascertaining that I can get much cheaper ink cartridges that numerous reviewers say will definitely be accepted by the printer. Such a shame... 07/03/2025: Ok, so now I very unhappy. Just received a new invoice (after I cancelled sub last month) for £24.15!! And this on a £1.99 per month 30 pages pm contract!!! I have had to call Epson support to get an email confirming closure of my account AND call the bank to prevent any further payments from that Merchant ID. You can imagine how much trouble that's been suffice to say its a morning of my life I will never get back. DO NOT, repeat NOT subscribe to Readyprint. Ever. 14/03/2025: Final word on this printer - Escaping the Readyprint Subscription service is possible(!) but comes at a cost. Your printer will be locked from the Epson server and you will NOT be able to print anything. Yes, you heard it here first! What to do? 1. Remove ALL of your ink toner cartridges that were acquired under the Readyprint subscription. Every one even though some of them may be 50% full (as in my case). 2. Replace them all with OEM cartridges [I'm using TopKolor and they work great]. 3. Lower the scan lid and attempt to print. 4. In my case I had to download the drivers again and create a new default printer instance and set up wifi access again (but you may not need to do that.) 5. The printer warns you that you are not using proper "kwalitee" Epson cartridges and goes on to do about 10 mins of "maintenance" buzzing and chugging. 6. Eventually, you will get your print(s). I've said it before, and I'll say it again. The Epson WF-3820 is really a very good printer. Just remember that all printer manufacturers make their real money from ink sales - hence the subscription/cartridge quality lock out racket. Enjoy! 12/01/2026 Update. Decided, finally, to update the firmware. If you look online, Epson is notorious for trying to force you to use their inks. Anyway, the update is now done...and phew! I can still print. I think the class-action legal case has forced them to climb down. Hooray!

Excellent printer - expensive ink!!!
Brilliant quality printing from a well-made and professional looking printer. Easy-ish to set up and speedy once in operation. The only criticism I can level at this printer is that the genuine Epson ink IS VERY VERY EXPENSIVE!!! The printer will accept aftermarket ink cartridges, however you do have to click through a series of warnings prior to starting to use them. Quality of the aftermarket cartridges on offer is not consistent either, so if you CAN afford it, go for the Epson ones. Sometimes there are some very good offers on ink multipacks, worth watching a few online and pouncing!! The Epson phone app is also slick and effortless, making printing direct very easy.

A3 full duplex printing and scanning. Large but powerful printer.
This is an excellent printer. Fast, capable of handling sizes up to and including a3. The automatic document feeder is wonderful and copes very well with double sided print. The printer inks are easy to change with a wide variety of replica and original inks available. The borderless print mode makes letters and other important documents look professional. The dual side printing mode eliminates the guesswork of enduring printing only odd on one side and then even on the other and worrying about correct orientation it simply prints on one side then takes the page back in and prints on the other side. The instructions were a little vague and might not be suitable for a first time printer owner or those who are technophobic. The paper trays can accommodate a large stack of paper meaning fewer changes needed and the output tray is simply superb as it automatically slides out to the right length for the paper used. I've used a lot of printers and this is my new favourite.

A nightmare to get working.
I have just purchased this Epson printer. The printer is happy, prints a local test page & prints a local page saying it is happily connected to the home LAN. I installed the full set of Epson software on my PC. These enable my PC to see the printer, connect to its configuration page, read ink levels, etc. BUT, I could not print anything, not even print a test page from the misleadingly-named Epson “Printer Connection Checker”. After 5 hours of wasted time, including 2 more clean installs, I managed to contact Epson Support. They asked for lots of information, but didn’t offer any useful advice. After another 4-5 hours of trial and error, I finally solved the problem (without help from Epson). Unlike my old printer, Norton Firewall insists that I have to explicitly trust this device. Maybe Norton knows something I don’t. Anyway, the printer now seems to work. When I feel brave enough, I'll try the scanner. After some months, my opinion of this printer has gone down. I have just spent an hour trying to print an A5 document on an A4 page, with enlargement. I followed what it said in the manual precisely. The printer came back with an error saying wrong size paper. I tried again with various settings, but always got the same result. It simply doesn't work. The Reduce facility seems to work. The Enlarge facility doesn't. October 2024. This printer is a REAL NIGHTMARE to set up. And this is my 2nd printer of the same type! See above. After 3 hours of complete frustration, I haven’t managed to print anything useful – just a registration page, and that was printed remotely by Epson. Nothing from my PC, not even the Windows printer test page. The Epson software on my PC can see the printer. It just refuses to print anything, with the highly informative error: Printer Error. And of course, Epson customer support is non-existent. I guess I’ll waste a few more hours before sending it back.
