Always send any other font selection sequence after the barcode data to tell the printer to stop barcoding.
Refer to the PCL5 printer guide from your printer vendor for more information.
A sample PCL5 font selection command is <Esc>(10U <Esc>(0p8hvbs4099T to select Courier font, size 10.
Do not forget to send the character symbol set selection PCL command (eg: <Esc>(10U for PC-850).
