I'm in need of finding out on how to mount and dismount printers.


In UNIX, printers are generally not mounted. The interface to the printer is a device file. This file is a kernel extension. The device file is written to just like any other file.

Writing to the printer device file is normally done via a shell utility which takes in the information to print, opens the printer device file, and writes to the printer: i.e. lp(), lpd() and other shell built-in functions.

Applications can also write directly to the printer(s) by opening and writing to the device file.
