N Printing connection issue post QlikView upgrade

[RickyK]

Hi All,

We have upgraded QlikView April 2019 to May 2022 today.

have done some sanity check and found an issue with NPrinting.

Some of our QlikView applications are using N Printing to generate Excel reports.

When I try to trigger the job in N Printing got the below error.

WARN: error during report generation: NPrinting Engine failed to open document: navigator=qlikview;documentpath="qvp://reportpath/abc.qvw". Check connection page for connection status.

When I check the connection status by run the verification, got below error:

attached the error snap.

please do the needful ASAP. Tq!

Your screenshot indicates that the server and client release aren't the same which should in general be avoided. Further I remember that there was a hint within the release notes that there is a change on the qvp-protocol which may prevent the communication between QlikView and NPrinting.

Hi Marcus,

Thanks for your reply.

Issue got resolved after installing the same version of the QlikView desktop in N Printing server.
