Virtual Printers are the mechanism Print Distributor uses to receive print jobs. You can create as many as you need and each one has it’s own defined actions that control what happens when you print to it.
There are two types of virtual printer available.
This is the default printer you should use for new applications. Internally it uses TCP/IP over a loopback address to receive print jobs which is reliable across all applications. By default the listening port starts at 9200 and increments for every new printer, you can change this in the options.
If you upgrade from Print Distributor 6 the virtual printers will all use the legacy virtual printer type. It uses a protocol called Named Pipes to receive print jobs. Some applications (Adobe Acrobat in particular) can have problems with this type so we do not recommend it for new applications.
Both the standard and legacy virtual printers have a Windows printer driver associated with them. This means all the printer settings such as which paper tray to pull from are set when the document is printed to the virtual printer. They cannot be overriden by settings in any of the physical printers.
