Certainly, but the command would be something like this:

convert rose.gif -crop 40x30+10+10  +repage  name.gif

where "rose.gif" is the original image, "40x30" is the pixels size to be 
cropped, +10+10 is the offset telling the command the offset in the 
image to position the crop +repage is so that the command reduces the 
"canvas" to the cropped size and "name.gif" is the name of the resulting 
image

Yup, and the command above would be modified to do that. (Sorry, I don't 
know how to pipe to a printer)  But what OP would need to know the 
dimensions of the original image, the dimensions of the crop and the 
dimensions of the  offset.   Pretty sure that is not what was asked for.

True, before you send to print, you can see the result with "display" 
which is also part of the IM suite like this:

convert rose.gif -crop 40x30+10+10  +repage  - | display -

(hint - "q" to quit the display window, right click for options)

Cheers,
