Which are the best Inkjet printers that work perfectly with Linux and Ubuntu operating systems?
A great source of information regarding printers that work well with Linux Ubuntu computers can be found at http://www.openprinting.org/printers/ They list printer models that work perfectly, mostly, and partially with Linux. There are links to printer drivers and documentation.
Looking at the lists it would appear that Epson printers seem to be the most Linux friendly. Among the currently available printers that are listed as working perfectly are the Epson Expression Photo XP760, Epson Workforce WF-2510WF, and Epson Workforce WF-2010W, using the epson esc/p-r generic driver.
If using a Linux based operating system, before buying a particular printer, we recommend you double check to make sure that it is compatible.
