Multiple Printer Ports

Starting with version 10.14 you can create multiple printer ports. This will support simultaneously printing to two PDF printers and therefore increase performance in an installation with multiple PDF printers.

Use Multiple Printers

One printer can only use one printer port. Therefore, you must install multiple printers if you want to use multiple ports. Each installed printer can either share a port with another printer or have it's own port.

Multiple printers are installed using the /PRINTERNAME command line switch on the installer. This means that you will have to run the installer from the command line to use this feature.

Additional ports are created with the /PORT command line switch. This is also an extra parameter that you can put on the installer command line.

Example

Here you have an example of an installer command line.

Setup_PDFWriter_bioPDF_14_4_0_2963.exe /PRINTERNAME="Extra PDF Printer" /PORT="EXTRA"

This will install a new PDF printer with the name Extra PDF Printer and connect it to a new printer port named EXTRA.

Notes

Extra printer ports are created under the print monitor branch of the registry.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors\bioPDF PDF Print Monitor

Each port is given a number starting with 1. If you later choose to remove a port, then you must rename another port so that the number sequence is still intact. If a number is missing, then Windows will not recognize all the ports.
