DataRay printers can also generate a label without interface to the network or Hospital Information System. The DataRay 2D barcode or Label Duplicator Code (LDC) allows healthcare professionals to print duplicate labels containing patient’s necessary information even if the Hospital Information System shuts down. This down-time solution allows labels to be printed at the patient’s bedside for immediate labeling of blood or other samples collected, leaving no room for confusion during transport to the lab or uncertainty of which sample belongs to which patient, narrowing the gap for human error and increasing protection of the patient.
