33
* The HP Color LaserJet 5/5M provides a rather unexpected speed/performance
36
* When generating rasters, only the fixed (simple) color spaces provide
37
* reasonable performance (in this case, reasonable != good). However, in
38
* these modes, certain of the fully-saturated primary colors (cyan, blue,
39
* green, and red) are rendered differently as rasters as opposed to colored
40
* geometric objects. Hence, the color of the output will be other than what
43
* Alternatively, the direct color, 1-bit per pixel scheme can be used. This
44
* will produce the expected colors, but performance will deteriorate
45
* significantly (observed printing time will be about 3 times longer than
46
* when using the simple color mode).
48
* Note that when using the latter mode to view output from the PCL
49
* interpreter, geometric objects and raster rendered with other than
50
* geometric color spaces will have the same appearance as if sent directly
51
* to the CLJ, but rasters generated from simple color spaces will have a
52
* different appearance. To make the latter rasters match in appearance, the
53
* faster printing mode must be used (in which the case the other objects
54
* will not have the same appearance).
