The Services For Macintosh service (SFMSRV) receives print jobs from Macintosh clients. From the client's perspective, a printer shared through this service looks just like a share on an AppleShare server or a stand-alone AppleTalk print device.
The SFMSRV assigns the RAW data type to all jobs targeted to PostScript printers and also assigns the PSCRIPT1 data type to all jobs targeted for non-PostScript print devices. For additional information about processing of Macintosh print jobs, refer to the section "Services for Macintosh Print Processor (SFMPSPRT)" later in this chapter.
