IMHO, because it would be awkward to specify options for a pseudofile. 
Since on unix you can pipe the output of one program (your app) to the 
input of another program (the print spooler), it's as convenient as a 
pseudofile. You could in fact create a pseudofile ("named pipe") that 
looks like a file but connects to the spooler daemon.
