Problem with Epson stylus T 11

I have a EPSON STYLUS T-11 printer with me.
I have a pdf file with the english text. When I give the print command, a printout comes with the letters jumbled up or some other unwanted letters are being printed on the paper.

For eg: For 'Cambridge exams' it prints 'JUXMISJTJJJAHASD32ZHHS HH0QWOOPAS9'.

I have tried with other pdf files. I did not get the printout at all.
What could be the problem?
Reply as soon as possible.

In that case i would suggest you to first convert your pdf document to word document by using Quick PDF Converter, after converting now try to give print out for the same. At the same time i would also suggest you to try to take print out of pdf file from another printer if you are facing same issue then it seems that there is some issue with your file.
