6.5. How to enable use of HTTPS between Print Spooler and Printix Client

All Printix communication inside and outside the network is secured with encryption and the use of HTTPS. Follow these steps to allow the PrintixService.exe to listen for print data from the Windows Print Spooler (spoolsv.exe) via HTTPS (TCP port 21343). Requires Printix Client for Windows version 1.3.1245 or later.

1. Select Windows logo key + R to open Run.
2. Type: regedit, and select OK.
3. In Registry Editor browse to:
   HKEY_LOCAL_MACHINE\SOFTWARE\
   printix.net\Printix Client\
4. Add the DWORD value name DisableHTTPPrinting and give it the value 1.
   Printix printers will within 10 minutes be converted to use HTTPS printing and have their Port changed from for example: http://localhost:21339/ipp/ASD/2114d3f3-e5732… to https://localhost:21343/ipp/ASD/2114d3f3-e5732…

*With a value of 1 Printix Client will within 10 minutes convert Printix printers to use TCP port 21343 instead of the previously used TCP port 21339. Printix printers will be converted back to use HTTP printing within 10 minutes after the registry has been changed back to 0 from 1.

!If Microsoft’s Windows Registry DWORD value name DisableHTTPPrinting in HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Printers\ has a value of 1 it disables both HTTP and HTTPS printing for the Windows Print Spooler and thereby Printix printing altogether. It is not possible to use Printix printing on Windows if a group policy (GPO) disables HTTP printing.
