Sealevel Port Devices Driver



A Windows printer definition includes a port and device driver. For standard output devices, you can use port and device driver pairs supplied by Microsoft or a printer vendor. For output and input devices unique to the Barr software, you can use the port and device driver pairs supplied with BARR/SPOOL.

Outdated drivers is one of the possible reasons why you are having issues using your USB device in Windows 10. We suggest checking and installing any available updates to troubleshoot the issue. To check for updates now, select the Start button, and then go to Settings Update & security Windows Update, and select Check for updates.

Different port and device driver pairs are used to direct data into and out of the spool. Which port and device driver combination you use in a particular instance depends on both the data source and the intended data destination. Drivers format data as it exits a program. Ports control the flow of data to its destination.

The port and device driver combination you use for a Windows printer for BARR/SPOOL depends on whether the Windows printer is a source or destination for spool files.

When you input files to the spool or output files from the spool, you must use port and device driver pairs that correspond to the file format. The original file will be in one of two types of file formats: Barr formats or printer-specific formats.

  • Files in a Barr format require a Barr port and a Barr device driver. Examples of files in a Barr format include files sent with Print Utility or files input from an NJE host with the BARR/NJE module.

  • Examples of files in a printer-specific format include files from a Windows program such as Microsoft Word. Files in a printer-specific or destination-ready Data formatted for its ultimate destination. For example, if the data is intended for a printer, it becomes destination-ready when it gets converted to the format the intended printer requires. format require a port and device driver from the printer manufacturer.

When you use a printer-specific driver on inbound spool data, the file is converted only once (instead of twice), which speeds overall processing.

The following links provide descriptions of the available ports and examples of their use.
