Printing Codabar on a thermal printer
A generated image is fine for a one-off. For a production run you want the barcode rendered by the printer at its own resolution, sized in whole dots so the narrow bar lands on an exact dot boundary. LabelInn does that on Zebra, TSC, Toshiba and Epson hardware, and it can drive one label per row straight from your data.
Frequently asked questions
Is this Codabar generator really free?
Yes. The generator runs entirely in your browser, there is no signup, and the downloads carry no watermark.
Does my data get uploaded anywhere?
No. The symbol is encoded locally in your browser. Nothing you type is sent to a server.
What can Codabar encode?
digits and - $ : / . +, with A-D start/stop characters. Length: variable. Check digit: none by default.
Can I print Codabar labels in bulk from a spreadsheet?
Not from this page — this tool makes one symbol at a time. LabelInn binds a spreadsheet column to the barcode field and prints one label per row on a thermal printer.
Printing Codabar labels in production?
This generator makes one symbol. When you need a batch — one label per row from a spreadsheet, a database or your API — LabelInn renders Codabar natively on the printer at its own resolution.
