A:AnswerHello Moises. You can connect multiple computers, smartphones, and tablets to the WF-7840. Please note that the number of supported devices will vary depending on your home network connection, print jobs, and resources used. Also, the printer does support automatically scanning 2-sided documents in black and white and color. Regards, Kevin - The Epson Team.
A:AnswerHi Fred, Yes the USB connector on the back of the WorkForce Pro WF-7840 is a Type-B. The printer does not include a USB cable. Regards, Mark - The Epson Team.
A:AnswerHello Erid. Unfortunately, we have not tested the WF-7840 with transfer paper, so we cannot guarantee print functionality. We recommend reaching out to the paper manufacturer to confirm compatibility, as this printer uses pigment-based inks. Regards, Kevin- The Epson Team.
A:AnswerI install these at job sites and connect them to Windows PCs, but you can get the correct driver from Epson for the MAC systems.

A:AnswerHi RoxyElaine, Using the rear feed tray, the WorkForce Pro WF-7840 is rated for 68 lb. paper. This includes double-sided printing. The rating was developed using Epson-brand paper, which is specifically designed for Epson printers, so third-party paper may not feed as well. The ADF can hold 50 11" x 17" sheets at a time. Regards, Mark - The Epson Team.
A:AnswerHi Bon, Unfortunately, we cannot test the WorkForce Pro WF-7840 with all third-party paper types, so cannot guarantee the print quality. To see a list of Epson paper types know to be compatible, visit the Epson support site for the WF-7840. Regards, Mark - The Epson Team.
A:AnswerHi MARC, We cannot test all third-party media in the WorkForce Pro WF-7840 so cannot guarantee that it will work, or have acceptable quality. Visit the Epson support site for the WF-7840 to see a list of paper types known to work with the printer. Regarding size, the largest sheet you can print in the WF-7840 is 13" x 47.2". Regards, Mark - The Epson Team.
A:AnswerYes. 4 cartridges (Black, Yellow, Magenta, and Blue). There is an available larger Black cartridge that you can purchase to replace the smaller one after use.
A:AnswerHello Jeckert. The WF-7840 does not use eco-solvent ink. The printer uses T812, T812XL, and T812XXL Epson Ink Cartridges formulated using pigment-based ink. Regards, Kevin - The Epson Team.
A:AnswerHi Daveyboy, You can print on 4.25" x 5.5" sheets using the WF-7840 by creating a User Defined size in the printer driver. You only need to do this once. We cannot test all third-party media so cannot guarantee print quality. Regards, Mark - The Epson Team.
