Problems with printing reports that appear to be Vault problems often are problems with the print command configured on the profile Reports tab. Therefore, you should test print commands from a command line on the server on which Vault is installed to ensure that they work correctly.
In some rare cases with Microsoft Windows, the print command works correctly when tested from a command prompt but does not work when configured on the profile Reports tab. The issue may be with how Windows calls the print command. If you experience such a problem, from a command prompt on the master server on which Vault is installed, enter the following command (use the appropriate server and printer names):
NET USE lpt1 \\servername\printername PERSISTENT:YES
