The EPSON EP-804A, EP-804AW, and EP-804AR are all models from Epson's EcoTank series of printers, which are designed to offer high print volume and low cost per page, thanks to refillable ink tanks instead of traditional ink cartridges. These printers are part of Epson's line of all-in-one printers (including print, copy, scan, and sometimes fax functionalities).

To use these printers on a Windows computer, you'll need to install the appropriate Windows driver. The driver allows your Windows computer to communicate with the printer and use all its features.
