Printing issue with Pages

With my MacBook Air and PAGES I typed a letter and printed it out on a HP Envy 4320. There were two lines of printing blurred. I then attempted to print it again and a blanks sheet came out. I tried this several times with the same result. Then I printed a couple of other documents from my desk top which printed fine. I then tried to produce another document in PAGES and print. Again several blank pages of paper. I can't print anything from PAGES now. At the beginning I got a messages to the effect the background was deleted or would not print. What did I do? How do I fix it?
