Hello, can anyone help with this - I was running W7 on a Dell laptop with Office 2013. Since upgrading to W10 eventually got Office 2013 to respond OK, but now when I go to print from Excel or Word (Epson XP-400 connected by USB cable) the printer goes thru its motions & thinks its printing, but all I get are blank pages. Have tried all the usual (turning off & on etc). HELLPP??
