I have a Europa Plus with a Test n Tag Printer which I have used for the last 3 years. I have now purchased a Primetest 350 and bluetooth adapter for the printer. I have used my remaining yellow test n tag labels with the primetest without issue.
The various sites where I can buy labels say I should use yellow with the europa plus and white with the primetest.
I would like to know why this is. Perhaps it is a throwback from the old type laminated labels?
