Remove all Unsupported Items including alternate states, sheet/document triggers, always one selected list/multi box properties from a copy of the QVW and use the copy for reporting purposes. For detailed steps and workarounds, please visit the links below:
-Log on as the NP service account. -Use 'File > Open in server" using the QlikView Desktop and connect to any QVW to pull the assigned license lease to the QlikView Desktop.
Destinations: Ensure that the NPrinting Service account has permissions/access to local folders and network folders if using local NP connections. These Windows 'share' and 'security' permissions are necessary to configure if you intend to distribute NPrinting reports to a network or local destination. To configure 'Destinations' visit Distributing reports to folders
Section Access: If you are using Section Access in your QVW or QVF, it must be NTLM section access and the NPrinting service account as well as the identity used in the NPrinting connection should be added to the section access load script as ADMIN access. Further you must use QVP connections when using Section Access. See Section access
Server performance: Check the QlikView Server and Qlik Sense server performance. If those servers resources are maxed out/fully utilized ie: CPU and Memory nearing 100 percent usage, NPrinting may fail to open any QVWs or QVFs.
Restart Servers: Check that the QlikView Server and Qlik Sense server services are fully operational and running. Restart these services on a regular basis to mitigate performance issues related to Windows Memory leaking. Rebooting servers on a regular basis is recommended for any Windows Server.
Keep in mind: In many cases due to certain defect fixes, upgrading often resolves connection issues when running older versions of NPrinting assuming thatthe information in this article above is first fully addressed. It is suggested that you upgrade to the most recent version of NPrinting available from the Qlik Support downloads site to leverage any recent bug fixes and performance enhancements. Always check corresponding product release notes and NPrinting system requirements before upgrading.
