In addition to the WF-4820 print and scan drivers, the WorkForce Pro software bundle includes TWAIN drivers for scanning directly into apps that support it. You also get Epson’s two excellent scanner interfaces, Epson Scan 2 and ScanSmart, as well as Epson Fax Utility. Our review of the WF-4830 goes into more detail about all these options, including their OCR software and plug-ins for specialized scanning.

The PrecisionCore Heat-Free Technology printheads that Epson uses in its WorkForce and WorkForce Pro printers consistently produce quality output that you and your business can depend on. PrecisionCore printheads contain more and smaller ink nozzles than most other inkjet printers, resulting in crisper, near-laser quality text.

What should I do? I can't print from my Mac with a wireless connection since I received an exchange product from Epson. What should I do? I was able to print from Windows before with an Ethernet connection, but now I can't. What should I do?

I was able to print from Windows before with a wireless connection, but now I can't. What should I do? AirPrint enables users to print wirelessly from within applications on Apple devices to AirPrint Compatible Printers connected to a wireless network. You can use your iPhone, iPod Touch or iPad to easily print via Airprint without the need to install drivers or configure the printer queue. Just tap 'print' and select your AirPrint compatible printer, and print!....It's that simple. Paper handling on the WF-4820 consists of one 250-sheet cassette that you can configure to hold up to 50 sheets of premium photo paper or 10 #10 envelopes. The WF-4830 has a significant advantage here with two 250-sheet cassettes that you can load up with your everyday paper or use for additional types of media, such as company letterhead or photo paper. This increased capacity and flexibility can greatly extend the amount of time between trips to refill or change the paper. Canon’s slow TR8620 (13.8ppm) and slower G4210 (8.3ppm) aren't even in the same class. Epson’s WF-C5790, on the other hand, achieves a comparable 24.4ppm. HP’s two OfficeJets, the Premier and the 9015, manage 17.4ppm and 22ppm, respectively, and Brother’s MFC-J5845DW scored 20.6ppm. I'm having trouble sending or receiving faxes over a VoIP (Voice over Internet Protocol) phone line. Why?For connecting to the WF-4820, you have Ethernet and Wi-Fi for networking, USB 2.0 for connecting directly to a computer, and Wi-Fi Direct and Bluetooth LE for direct connections to mobile devices. If you're upgrading from the WF-4720, you may be used to a near-field communication (NFC) button that allowed you to connect your phone or tablet to the printer by touching it to an NFC hotspot on the control panel. NFC was a hot feature for a hot minute but didn’t really catch on; the WF-4820 no longer has this function. However, it has plenty of other ways to talk to your handheld. Standard interfaces are Ethernet 10/100, Wi-Fi 802.11 b/g/n/a/ac, USB 2.0, Wi-Fi Direct, and Bluetooth LE (Lite Edition).

I tried to install the product in Windows with a wireless connection, but the installation failed. What should I do? I can print with a wireless connection on my home network, but not on a VPN (virtual private network). What should I do?

There are also a wide variety of third-party apps available to enable wireless printing through Apple devices, even to machines that are not natively AirPrint compatible printers. By sharing a printer installed on an Apple Mac or Windows Pc over a wireless network any printer may be able to take advantage of the AirPrint features. (An additional third-party app may be required to be installed on the local machine) If you can open it on your apple device, chances are you can print it with AirPrint and an AirPrint compatible printer. Airprint works with Safari, Mail, Photos, iWork, PDF's in iBooks and many third-party AirPrint compatible apps available from the app store.
