问题
I'm looking to add the functionality to print multiple labels using a Dymo LabelWriter 450 Turbo. I've downloaded the DYMO-Label-v.8-SDK.dmg from the Dymo site but can't see any Javascript/web related SDK files or documentation - all I can see are AppleScript examples which won't help here.
Does anyone know if this is possible (data for labels will come from backend database connected to PHP web app). I can't find any documentation for a Javascript SDK on the Dymo Developer website - only some examples from a few years ago so not even sure what is the current state and which is the latest version etc and whether there is a way to print multiple labels?
回答1:
I actually just built this functionality in my own web app using the exact same printer and I'm feeling friendly today. Here is what I have working for me in a production level application. Good luck!
