fax-resolution OBJECT-TYPE
SYNTAX OCTET STRING (SIZE(1..64))
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"struct {
unsigned_32bit x_res; /* 1st four bytes; big endian */
unsigned_32bit y_res; /* 2nd four bytes; big endian */}
Sets the send fax resolution. The x and y resolutions
in this object are in fixed-point with 16 bits of
fraction, and 16 bits of integer, and are in dots per
inch. X is horizontal; Y is vertical.
Examples of computing x_res and y_res:
300 dots/inch:round(300 * 65536) = 19660800
16 dots/mm: round(16 * 25.4 * 65536) = 26633830.
If the device does not support the given combination,
then it'll select the nearest supported values in a
device-dependent manner (documented in the POS).
Additional information:
HP Laserjet 3200 supports 4 fax resolutions. As far as the
end-user is concerned these resolutions are: standard,
fine, superfine, and photo. Photo is not really a
resolution--see more below. Standard is the default.
Resolutions map as follows (values are given in dots per
inch (dpi) horizontal X vertical (x X y)): standard(203
X 98), fine(203 X 196), superfine(300 X 300), and
photo(300 X 300).
Supported resolutions in hex notation (dpi, x X y) are:
standard(00cb0000 X 00620000), fine(00cb0000 X 00c4000),
superfine(012C0000 X 012C0000), and photo(012C0000 X
012C0000).
The device ignores attempts to set invalid resolutions.
Photo is not a resolution, but photo setting depends on
whether half-toning is on or off. In the case of HP Laserjet 3200
photo setting doesn't actually change the bits going out
the modem -- still one bit per pixel so photo and
superfine are the same.
NOTE: The last 16 bits of the horizontal and vertical
settings are ignored. Only the first 16 bits of the
horizontal and vertical resolution setting are used."
