Specify Epson model number (e.g. 400, 500, 600). (You can also specify the model
number in the command. For example, Pp.escp2.600 indicates
the Epson model 600.)
-ocn
Adjust cyan gamma correction (where negative is lighter, positive is darker).
-odn
Set printer graphical depletion (default: 0 is disabled).
Ranges between 2 and 5 where a value of 2
removes 50% of the pixels, 3 removes 33% of the pixels, etc.
If you're printing to an Ink Jet printer, use this option to deplete the amount of ink
that's used when printing solid colors. It can prevent the paper from
getting soaked.
-oDn
Specify ink dot size. Range is 0 to 4.
-oL
Fractional string-extent loop limit. The maximum number
of iterations that the sting-extent algorithm attempts
to fit a string into the required bounding box.
(Default: 3. For quicker, but sloppier text, use 0.
Values greater than 6 aren't recommended.)
-of
Enable Floyd-Steinberg dithering (default).
-ogn
Adjust black gamma correction (where negative is lighter, positive is darker).
-oh
Halftone dithering (default: "-of").
-omn
Adjust magenta gamma correction (where negative is lighter, positive is darker).
This utility converts .phs output for an Epson ESC/P2 printer.
The Pp.escp2 driver is usually used as a part of lpsrvr or
called directly from the prsetup configuration.
