6.5.10 OPOS Drivers for the Receipt Printer
The receipt printer OPOS drivers are included in the HP factory image and are also available
from HP.COM.
Note: If you are using the serial printer, one will need to uninstall the OPOS drivers and then
re-install the OPOS driver (see details below of installation). HP OPOS driver version
1.0.1.34 (or later) supports the serial receipt printer.
OPOS driver 1.0.1.21 (or later) for the receipt printer will work with the printer in either NATIVE
or PRINTER CLASS mode. During the installation process of the OPOS driver one will be
prompted for which mode the printer is in (PRINTER CLASS is selected by default).
The Windows mini-drivers and the OPOS drivers cannot be set to the same COM port.
