Printer security levels affect how rights to a printer are determined and enforced. The default security level is Medium. With sensitive print data, you might want to set the security level to High; however, performance will be effected.
To set a printer's security level, do the following:
In iManage, click iPrint Management > Manage Printer.
Browse to and select the printer you want to enable Access Control for.
Click the Access Control > Security.
Select the level of security you want for the printer.
Click OK or Apply to save your changes.
