Printer name error cannot be shared

In a local area network, a cannon printer is shared and named after the cannon. The local printer is normal when there is a sudden inability to print online. On other computers, however, the display printer is in the "Offline use printer" state, and the print icon is also grayed out.

This occurs when you first suspect that there is an error in the print port, that you add a print port to the printer's properties, that the network print port is correctly added, and that the original port is still unable to print online.

In My Network Places, look closely at the printer's information to see if the name is consistent. Check found that the name of the tail add a space, remove the space, printing can return to normal.

The printer name is the same as the file name, you can add a space at the end, but when the network print port is added, the trailing space will be treated as an invalid character, resulting in a discrepancy with the actual printer name.
