Are there particular settings within FortiClient that blocks access to a printer?
We are running the most current version of FortiClient on a Windows 10 machine. There is an HP LaserJet Pro MFP M426fdw printer on the network that works perfectly fine when FortiClient is turned off, but as soon as it is turned back on all printing is block and errors are displayed.
Last year I had a similar problem with HP CLJ M570. After update FCT to 5.4.2 (or 5.4.1) issue was resolved. I recommend also installing the printer based on the IP address instead of a host name - it also helped.
