J - JPEG Image Quality
Sets the desired quality when the JPEG image format is selected.  Higher 
numbers result in higher quality, but larger files.  Smaller numbers result in 
greater amounts of lossy compression, faster transmission times, lower 
quality, but smaller files.  
(Default =  50)

K - Gamma Correction
Gamma measures the brightness of midtone values produced by the 
image.  You can brighten or darken an image using gamma correction.  A 
higher gamma correction yields an overall brighter image.  The lower the 
setting, the darker the image.  The optimal setting for text images is 50K.

L, R, T, B, M - Image Cropping
Note: Image Cropping should not be used with IMGSHP Modifiers (see 
page 8-5).
Ships a window of the image by specifying the left, right, top, and bottom 
pixel coordinates.  Device columns are numbered 0 through 1279, and 
device rows are numbered 0 through 959.
n
L The left edge of the shipped image corresponds to column 
n
 of the 
image in memory.  Range: 000 - 843.  
(Default =  0)

R The right edge of the shipped image corresponds to column 
n
