You should print the title page if there is one. If your score includes a title page, it has been added to cause the page turns in the music to fall in optimal places. The title page should be printed on the first side of the first sheet, with the first actual page of music on the back. This will cause the first and second pages of actual music to sit side-by-side when the score is opened up. Don't print the title page on its own single-sided sheet. Omitting the title page to save paper may result in awkward page turns.
