Barcode printers need to be calibrated before use to ensure that the printed barcodes are accurate and scannable. Calibration involves adjusting the printer's sensors and other settings to match the specifications of the labels being used. If a printer is not calibrated, it may produce barcodes that are too small, too large, or otherwise distorted, making them difficult or impossible to scan.
Therefore, it is not recommended to use barcode printers without calibration. The calibration process typically involves printing a test label and making adjustments until the printed barcode matches the required specifications. This process may vary depending on the specific printer model and label type being used.
It's important to note that even after calibration, barcode printers may require periodic maintenance and re-calibration to ensure they continue to produce accurate and scan-able labels.
