drawing a Barcode without a Barcode font

Our thermal prints, both qrcodes and barcodes, are scannable w/o problems with our iOS devices. So resolutions is not a problem.

Although we were able to successfully print the labels and are awaiting a positive confirmation from the carrier, i will try to import a snapshot of the barcode and will check if that prints look better.

Regards,

Figure out the minimum resolution you are printing to, then make your bars and white spaces in some increment of that, then screenshot and scale as necessary. We have ERP software that prints barcode labels for inventory, but the barcode readers that use the iPhone camera don't read them well, probably because the barcodes are printed with a thermal printer and the resolution kinda sucks.
