In AutoCAD you might get a message saying “This plotter configuration cannot be used for one of the reasons : The driver cannot be found, the device cannot be found, or the driver has a problem”
Now before that error message it will list a printer (ex: RICOH Miafa 1080 : This plotter configuration cannot be used..) and in this case that printer (RICOH) was NOT installed nor on the network at the client.
AutoCAD saves the ‘plotter’ information within its projects and not inside the software itself.
To fix this you would have to open each project file, go to print, ignore that error message, select the correct printer and click APPLY TO LAYOUT. That will save the project file to always print to the correct printer by default. It is important to SAVE the project file after you print otherwise the incorrect print setting will come back.
