Something Euro-stylish. Computer fonts were not en vogue in the 1960s. But there are a few fonts now that try to look like those Dymo tapes.

Don't know which typeface was used originally, but Dummytapes is a decent approximation of the finished product.

Thanks for the help. I am not looking for a label looking font but what the machines used as letters. I want to update my font “Impact Label” to include some extra glyphs (@ # $ etc.) and want to keep it in the correct face if I can. I may have to just make up my own.

Totally appreciate your time and help. Cheers.
