JSI Tip 1078. Event ID 19, Sharing printer failed.

If a printer share is no longer available, and your event log contains:

   Event ID: 19
   Source: Print
   Type: Error
   Category: None
   Description: Sharing printer failed, \<print share name>.

it could be that you were over zealous in documenting the printer and included more than 256 characters in the comment field.

Reduce the size of the comment to less than 256 characters and restart your computer.
