Description: The fuser temperature to be used when printing media from Tray 1. The value zero is the default temperature. Values less than zero are progressively lower and values greater than zero are progressively higher. The range of values supported is device specific. Additional information: Laserjet 1220 supports 4 fuser temperatures. Zero (0) is the default temperature, one (1) is a higher temperature (for use on media like cardstock), two (2) is an even higher temperature (for use on rough media), negative one (-1) is a lower temperature (for use on media like transparencies). Setting to an unsupported value causes the printer to snap to the nearest supported value and to return status along with the actual value that was written. The snap values are as follows: <=-1 snaps to -1 >=2 snaps to 2
