Non-Windows applications do not interact directly with the spooler. Instead of printing to a printer, they print to a port, such as LPT1. The flow control depends on what other software is using that port. If the target port is managed by a network redirector (the user has issued a Net Use \\\ command), the job goes to the appropriate redirector (the Windows network redirector or the NetWare network redirector).

If neither the redirector nor a printer are involved, the job goes to the parallel or serial driver that controls the target port and the print device receives the job.
