Automating Printing Copies

Hi!

I am hoping someone can help.  I have a spreadsheet of classes with the number of students in each class.  I want to automate either printing copies of the same one page document using the class count column or mail merge the needed copies into a single document to print at once.  Clicking print and typing in the number needed 23 times is very tedious!  As is counting the copies by hand. 

Any ideas?

Thank you!
