This is awesome. I'm a solo dev and I created an electron app named Label LIVE. I recently added an HTTP API so you can fire off label jobs using a POST request (or retrieve label PNGs via GET). What Label LIVE affords is a WYSIWYG imaging pipeline that can target many different thermal printers at the correct DPI, or generate/submit PDFs to a printer (system or network). If you mention this note and your project, I'll send you a free license for "testing." :D (and no, no direct Linux-Desktop support yet, sorry!)
