Try printing something from a different program. (e.g. copy & paste your quiz questions into Microsoft Word, OpenOffice Writer or similar and print from there - or try printing a photo from whichever software you use to view pictures).
If the problem disappears then clearly it's linked to WordPad; if it remains then it relates to either the printer or its drivers. (if it's the latter give Epson UK Support a call tomorrow between 0900 and 1800 on 0343 90 37766. Calls are charged at the same rate as those to 01 or 02 numbers which means that if you've got 'included minutes' on your mobile phone deal, or a landline contract that includes calls to 01 or 02 numbers, it will be free to you).
