Direct Thermal and Thermal Transfer
Choose direct thermal or thermal transfer according to label life and operating conditions, covering both short-term workflow labels and durable labels.
YL-RP300
4-inch Desktop Label Printer
YL-RP300 corresponds to the Zebra ZD621 4-inch desktop printer, with direct thermal and thermal transfer printing, 203 dpi or optional 300 dpi, wired connectivity, and optional wireless connectivity. The current specifications do not include an RFID encoding module or protocol, so RFID projects require separate confirmation of the exact model and supplied configuration.
