Can not use printer from computer - letters, etc from email

Yesterday I wanted to print a letter I wrote - composed it where I do my emailing.

tried to print it but got this message:

"Some printing functionality is not currently available"

I copied the letter and pasted in my Word which did print it.

I emailed Epson and they sure did not answer my question - what happened and how to fix it.

I tried unplugging the printer for 5 mins and plug in again but nothing but same message.

I updated the printer program and still get the same message.

Not sure what the message means, nor do I know what to do to resolve this problem.

Is there anyone of you can tell me what to do?
