I was wondering if there is a way to select a certain amount of invoices (I.e. a quarter) and print them in bulk as at the moment I have to print them one by one

Hello info1655, 

Welcome to the Community page, 

So in order to do this you will need to

Go to sales on left hand main navigation bar>click on invoices> change the date to what you want it to be so for example 3 months>tick the little top square next to date column if you want all them ticked or you can tick which ones you want> then click on batch actions>print and this will print off all the ones you have marked with a tick.
