6.9.3 OPOS Drivers for the Scanners There are no OPOS drivers needed for this device if the device is used in the human interface device (HID) keyboard emulation mode. When the device is in USB-COM mode (OPOS) a Windows device driver is required. The required device drivers that support the scanner are included in the HP factory image and can be found on HP.COM. 6.9.4 Testing the Scanners 6.9.4.1 Testing scanners in non-OPOS The default mode of the scanner is non-OPOS mode when shipped from HP. In order to test the scanner in non-OPOS mode one can open an application like Microsoft Notepad and scan a barcode when the scanner is in default scanner mode. You may use one of the barcodes below for testing if you do not have an item with a barcode handy. 6.9.4.2 Testing the scanners in OPOS The scanners must be in USB-COM mode (OPOS). If one is not sure what mode the scanner is in, open an application like notepad and scan a barcode. If the scanner is in OPOS mode, when you scan a barcode nothing will appear in Notepad. If something appears in Notepad, the scanner is in USB HID Keyboard emulation or USB-Composite mode. In order for the scanner to work with OPOS driver, the scanner must be programmed into the USB-COM mode (OPOS). All configuration barcodes can be found in the Programming Guide on HP.COM. The following is an overview of the steps to test the scanners followed by more detailed steps: 1. Open ScannerTest. • C:\\HP\HPScannerOPOS\ScannerTest.exe. 2. Select the Scanner in the Scanners box.
