Based on your advise, I created a case with Qlik and received the following answer and worked fine to me !

1. Stop all NPrinting services

2. Open file pg_hba.conf at C:\ProgramFiles\NPrintingServer\data

3. Change METHOD from md5 to trust. Save the file

4. Start only QlikNprintingRepoService

5. Open file pgadmin3.exe at C:\ProgramFiles\NPrintingServer\pgsql\bin

6. Clik Add a connection to server

7. Use the following details in New Server Registration

Name: Nprinting

Server: localhost

Port: 4992

Maintenance DB: postgres (select from pull down)

Username: postgres

Password: Left the field empty

8. Once connected, select Nprinting then go to File > Change Password

9. Enter your old password (empty again) and new password (x2) as requested

10. Now stop the QlikNprintnigRepoService as well

11. Update the "pg-password" key value stored in these 2 config files to the new password:

C:\Program Files\NPrintingServer\NPrinting\WebEngine\webengine.config

C:\Program Files\NPrintingServer\NPrinting\Scheduler\scheduler.config

12. Change METHOD from trust to md5. Save the file
