Many printers implement barcode printing natively.
|

This hardware renderered barcodes are fast but the supported formats are limited by the printer itself and different between models.
|

However, almost all printers support printing images, so barcode renderization can be performed externally by software and then sent to the printer as an image.

As a drawback, this operation is much slower and the user needs to know and choose the image implementation method supported by the printer's commandset.

Often you can check the IP address by triggering the self-test of the device. As a next step try to send text
