Once you have your receipts set up on one machine you can export your receipts, and then load them on to another machine. Just remember to Save Locally once you import the receipts on the new machine.
As you can only save a template on to the computer you are working on you will need to export the template if you have more than one computer that prints out receipts (i.e., more than one computer on the circulation desk, or another computer in the workroom that you use to checkin items or capture holds with)
Clearing your browser’s cache/temporary files will clear any print template customizations that you make unless you are using Hatch to store your customizations. Be sure to export a copy of your customizations as a backup so that you can import it as needed.
If you are modifying your templates and you do not see the updates appear on your printed receipt, you may need to go into Administration → Workstation → Stored Preferences and delete the stored preferences related to the print template that you modified (for example, eg.print.template_context.bills_current).
