Hi Sarah,
Welcome to the community!
I'm sorry to hear your printer messed up, but don't worry we will get this sorted so you can get another hard copy printed off right away.
In order to re print pay slips, please go to 'File'>'Print Forms'>'Pay Slips.'
Once the menu box comes up, change the date range in the top right hand corner to match the pay period in question, then all relevant payslips will appear with an option to check each one you need, and print or email them.
Let me know if this works for you.
Thanks,
Chris.
