Epson Stylus C670 printer not printing...

Question

My mother's printer will only print e-mails but not spreadsheets nor web pages. I have uninstalled and reinstalled the software and it has plenty of ink. Sometimes the paper will go through and it sounds like it is printing but nothing shows up. Other times the paper won't even go through and it's like the printer is not getting the info. I have checked all cables, etc.
