Hello, friend!
To enable a home printer, connect it to the USB port of the home gateway (ONT). The IP address of this printer is the IP address of the ONT. This printer can be used after it is searched out and its driver is installed.
Do not remove and re-insert the USB storage device in use, because this may damage files in it.
A file (such as PDF) may fail to be printed in the Windows OS in any of the following cases:
The Windows domain is used and the user domain fails to be authenticated.
An alias is used to access the printer.
No authentication mode is used for a printer.
This issue occurs because of application program incompatibility. If this issue occurs, check your Windows or printer settings.
If the security software is installed on the PC, which leads to Samba user name authentication failure for the first login attempt, authenticate the user name again or use the Samba function in anonymity.

Thanks!
