For writing & printing music Finale & Sibelius are the industry standards. I've used Finale off & on for a decade. It has pros & cons. But for printing the sheet music, it's definitely excellent.

This program looks free & similar, but I can't vouch for it as I've never used it.

Hope this helps. Best of success!
