Issue:
From Windows 10 (some printer Controllers), there could be some issues regarding mounting Linux Caldera Public shared folder, especially after some WIndows Updates.
Solution:
1) First try deactivating Windows and Application Firewalls.
2) Search Bar > "Turn Windows Features On/Off"
3) SMB 1.0 : check both boxes
4) Search Bar > gpedit.msc (or "Edit group policy") > Enable insecure guest logons
5) Reboot Windows and retry.
