Download Labels Print File
Sometimes you might not be able to integrate OpenSpecimen with the printer due to network issues. E.g., in a multi-site study where the printers are in a collection site outside the VPN. In such cases, you can download the labels print file and upload it manually to the printing software like Bartender.
This is also useful during testing to check that the print rules are correctly configured properlyduring testing. This avoids having the testers to login log in to the server VM to check the content of the print files.
