NPrinting engine remains offline

[#1]

I installed QlikView in SERVER1 and Qlik NPrinting in SERVER2.

When I added a NPrinting Engine, the engine remains offline instead of online. This stop me from creating report.

I have searched several thread but no give a clear answer. I am new to Qlik Nprinting and try my luck here. Hope someone can tell how to fix this - Jack.

Here are some ERROR in nprinting_engine log

Maybe this helps?

NPrinting 17 added Engine in web client remains Offline

1. Make sure the engine server name is correct.

2. Make sure you have installed QlikView desktop client in the NP server and licensed (File -> Open in Server and lease a license from QV server).

3. Restart the Engine service.

Maybe something don't work when you tried to activate a licence in your service. Try clear license and put a licence again.

Install NPrinting on Same Sever as QlikView Desktop will solve the issue. Is it possible we install NPrinting and QlikView on separate sever or is it necessary to do so?

[Daniel_Jenkins]

Hi Jack,

You need a duly licensed QlikView Desktop installed on every machine where NPrinting engine is installed if you want those engines to use QlikView connections (as opposed to Qlik Sense connections in which case QlikView Desktop is not required). Take a look at: Software requirements > Qlik NPrinting Engine computer section here: https://help.qlik.com/en-US/nprinting/17.2/Content/DeployingQVNprinting/System-requirements.htm

HTH - Daniel.

[NZFei]

If you need to set up connection to a QlikView server, you must install QV desktop in the NP server.

Details are in the help page:

System requirements for Qlik NPrinting ‒ Qlik NPrinting

Highlight:

Software requirements

Qlik NPrinting Engine computer:

• Operating system: Microsoft Windows Server 2012 or Server 2012 R2. Only 64-bit architecture is supported. Microsoft Windows Server 2008 R2 is currently unsupported if connections to Qlik Sense are required.
• QlikView: QlikView Desktop 11.20 SR5 or higher and 12.00 SR1 or higher are both supported. If QlikView Server Enterprise Edition or Small Business Edition is installed, you need QlikView Desktop. QlikView Desktop Personal Edition is not supported.
• The user who runs the Qlik NPrinting services must have an active license for QlikView Desktop. You can use a license code and control number, or you can assign a Named User CAL from your QlikView Server. Do not use shared licenses because when Qlik NPrinting opens the local QlikView Desktop, the license must be active or the report generation process stops.
• QlikView Desktop must be installed locally on the same physical or virtual computer as the Qlik NPrinting Engine.
