The damaged printer has been disposed, cannot find it so cannot compare. Connected the replaced printer to the workstation, the printer didn't work. Print job was redirected to the backup printer. Re-calibrated the workstation, didn't work either.

When connecting the printer to another workstation (WKS5A08, the same model), the printer worked.
Perhaps the RS232 interface issue on the workstation?
