If the printer driver name displayed at the top of the [Printer Information] dialog box and the printer name displayed as [Name Retrieved from the Printer] do not correspond correctly, you may not be able to use the printer functions correctly. If the names do not correspond, delete the printer you have added in [System Preferences] and add it again. For details, see the Printer Driver Guide (see "Installation").
The display may vary according to the operating system, as well as the type and version of the printer driver.
