This can occur when the Price type on the ticket is too long. Shorten the price type name:
  1. Go to Tickets > Program search > Select the program you are printing tickets for
  2. On the price types tab, click "Edit"
  3. Remove/add any prices to the list to shorten the price type names
Note: To access and edit the global list of price types, go to Tickets > Ticket Sales Setup > Price types

If this issue is only occurring for one printer, contact your local IT to update the printer driver.
