Universal Printer Driver helps you manage multiple printer devices via one single driver

  1. Unknown devices would be listed as such and marked out with a yellow question mark. Select the unknown device or other device for which you need drivers and right click to access Properties. In the Properties window click on Details tab and select Device Instance Id or Hardware ID from the drop down.
  2. Recommended Resolution. Reinstall the device driver manually. From Start, search for device manager and select Device Manager from the results. Right-click the device in the list. Select Uninstall from the menu that appears. After the device is uninstalled, choose Action on the menu bar. Select Scan for hardware changes to reinstall the driver. Note You may be prompted to provide the path.
  3. Tips for better search results. Ensure correct spelling and spacing - Examples: 'paper jam' Use product model name: - Examples: laserjet pro p1102, DeskJet 2130 For HP products a product number. Examples: LG534UA For Samsung Print products, enter the M/C.

Busy and demanding business environments often have multiple OKI networked printer devices to support them which usually require the instalment of a number of different drivers by each user. This in turn needs to be managed by the IT department taking up time and resources.

OKI’s Universal Printer Driver has been developed to simplify the task of managing multiple printer devices via one single driver. By installing OKI’s Universal Printer Driver, users will have quicker and easier access to any PCL 5 supported printer or MFP on their network, regardless of printer type through one common user interface. So, if a printer is out of use, users can access uninterrupted printing by using an alternative device without the hassle of installing a new printer driver. This also results in less helpdesk calls and less pressure on your IT department as the need to install or uninstall new printer drivers will be a thing of the past.

If a multifunction PCI device conforms completely to the PCI multifunction standard, the PCI bus driver enumerates the individual functions. The PCI bus driver manages the fact that there is more than one function residing at a single device location. To the rest of the system, the individual functions operate like independent devices.

Vendors of a PCI multifunction device on an NT-based platform must do the following:

These multi-function steering wheels, as some companies call them, improve driving safety by putting the most commonly used controls in one of the most convenient places possible - right at the driver's fingertips. A driver's eyes and hands are extremely important tools for driving.

  • Ensure that the device conforms to the PCI multifunction specification.

  • Provide a PnP function driver for each function of the device.

    Since the system-supplied bus driver handles the multifunction semantics, the function drivers can be the same drivers that would be used if the functions were packaged as individual devices.

  • Provide an INF file for each function of the device.

    The INF files can be the same files that would be used if the functions were packaged as a individual devices. The INF files do not need any special multifunction semantics.

For example, the following figure shows the sample device stacks that might be created for a multifunction PCI device with ISDN and modem functions.

As shown in the previous figure, rather than enumerating one multifunction device, the PCI driver enumerates two child devices. The PnP manager treats each child device like a typical device, locating INF files, loading the appropriate drivers, calling their AddDevice routines, and so forth until a device stack is created for each device. The PCI driver arbitrates the resources for the child devices and manages any other multifunction aspects of the device. The vendor of the multifunction card provides function drivers and INFs for the ISDN and modem devices, just as if they were separate devices.

The illustration focuses on the function driver and bus driver for each function and their associated FDO and PDO. Any filter drivers (and filter DOs) are omitted for simplicity.
