Which symbology should I pick?

Code128 for short alphanumeric labels (most general-purpose). EAN-13 for retail product barcodes outside North America. UPC-A for North American retail. Code39 for older industrial inventory systems.

Can I print directly?

Yes — download the SVG for vector printing at any size. SVG barcodes scale without loss of quality, making them ideal for labels and packaging.

Is this distinct from /qrgen/?

Yes. QR codes are 2D matrix codes; barcodes are 1D line codes. They are not interchangeable — point-of-sale scanners use 1D codes; phones decode QR for URLs.
