When an MS-DOS client (including Windows 3.1 and Windows for Workgroups clients) sends a print job, the Server service running on the Windows NT print server receives the job and assigns it the RAW data type. Windows NT does not alter the job unless the Default Data type for the printer has been changed to RAW [FF Auto], or RAW [FF Appended], or TEXT. The Windows NT printer driver is never involved initially creating the print job, and is only involved in altering the job if the printer's default data type is TEXT.
