Show HN: Easily Generate Sequential Barcodes (getbarcodes.online)

I've been scratching this itch for a while now. My wife needed a tool where she could generate lots of simple barcodes, that would automatically align for printing on label sheets. Luckily she married me, and here we are with version 0.0.1 of getbarcodes.online. Probably not the easiest barcode generator, but alas it's a side probject.
