Google Calendars - backups and printing

I have a google calendar for every aspect of my schedule (i have a calendar for every class, for work, for appointments, and for personal reminders)

i would like to back up all these calendars together at once, as one file - is this possible?

the only reason i split up into so many calendars is because i wanted each type to have its own color

also, i want to print what i see on my google calendar for the entire semester, but it seems to only want to print out one week or month at a time, similar to my backup problem - i want to be able to print out every week (showing all of my calendars) for the entire semester, is there any way i can do this?

thanks for your help
