Mixed printing

Printing that mixes upper case and lower case letters should give you more information than the other two styles because you do have zones. It is also more likely this style could have a slight slant to the writing.
Any style of printing can have a superfluous stroke acting as a lead-in, connected letters, or a slant but it is most likely to appear on mixed printing. Even in printing when letters connect it is an indication the writer is able to connect his or her thoughts together. Also that they are friendly and outgoing needing contact with other people.
As with cursive writing the three zones and their size show the focus of the writers life. If the upper zone is larger they have more mental activity and often use this as a defense that keeps other people at bay. They steer clear of personal discussions preferring to talk business, philosophy or other non-personal issues.
A large middle zone indicates the writer focuses on the day to day life. They seldom have plans beyond the immediate future.
The large lower zone indicates a person who is more physical. They may watch sports if unable to participate, crave more material possessions, and be more in tune with their instincts.
