That is true, but there is another way that would be closer to the 
"stdprn" method (which I've never heard of either).

If you open a "pipe" file (popen) to the print command, you can write
data to the pipe file just like a normal disk file, and whatever you 
write to the pipe will be printed when you close it.

Just like what I envision "stdprn" would be!   :-)
