Removing site number from confirmations

Q: How do I keep the site number from showing on confirmations?

A: Go to Maintenance / Printing Options / Reservations, and select: Use the Site "Type" on confirmations instead of the site name.  

Note: In older versions, this option is under Maintenance / Printing Options / Receipts.

Also be aware that since this is in the Printing Options, it's separate for each workstation.  So you need to change the setting on each computer.
