Thank you, Alavahalf, for pointing out how old that printer is.
According to the Epson UK website, there are no drivers for the RX245 printer after Windows XP. (i.e. Windows Vista, 7 and 8 aren't supported). The XP driver was issued in 2004.
So if you're attempting to use the printer with anything after Windows XP it's unsurprising that you're experiencing problems. As your printer must be about 10 years old, it might well be time to look for a new printer. If you do, ensure that you look for one with separate ink cartridges for the different colours, as it will save you a fortune in the long run. Canon printers are the best rated in many surveys and this is superb (with cheap compatible ink cartridges easily available)
