There is a difference between the way the te'amim appear in the old hand-written codices and the way they appear in the first printed bibles. The first thing we notice is the diagonal lines where we expect curved lines for תביר, פשטא, גרש, גרשים, קדמא, מרכא כפולה, גלגל, מרכא, טפחא . In addition, several of the te'amim were changed more radically, such as זרקא and פזר.
