Each of these is described in detail in its own man page. Of most
interest is pconf_detect_printer(). This function will execute one of
the detection methods and return an array of character strings, each
representing a single detected printer.
The actual format of these strings will depend on the detection
method. For parallel port detection, the string will be in the basic
form: "port=p;model=m". For a network printer the form is:
"printer=hostaddr;vendor=v;model=m".
This library is intended for use by printer detection and
configuration tools.
