I have installed nprinting server , which got installed successfully.
But My Qlik Nprinting Web engine and qlik nprinting scheduler service are getting stopped automatically after few secs.
I am getting below mntioned error in log files:

I think you missed the following step (from Qlik NPrinting official Release Notes):
Upgrade to November 2018 or newer If you are upgrading to September 2019 Technical from September 2018 SR2 included or older version you must:
Open port 4997 outbound on Qlik NPrinting Server and inbound on all Qlik NPrinting Engines
Reinstall all your Qlik NPrinting Engines and providing a password for certificate exchange
Open the Engine manager in the Web Console
Open the detail page for each Engine and send the certificate after inserting the same password you used during the engines reinstallation
Qlik NPrinting Engines stay offline until the certificate exchange is performed. Older Engine versions cannot connect to a Qlik NPrinting September 2019 Technical Server.
I suggest you to upgrade to latest version, June 2019, to benefit of all solved bugs.
