This was the last remaining printer using the "sixel" and "sixmap"
support, so those functions were removed as well.

-The current version of \fIxpr\fP can generally print out on the LN03
-most X windows that are not larger than two-thirds of the screen.
-For example, it will be able to print out a large Emacs window, but
-it will usually fail when trying to print out the entire screen.  The
-LN03 has memory limitations that can cause it to incorrectly print
-very large or complex windows.  The two most common errors
-encountered are ``band too complex'' and ``page memory exceeded.''
-In the first case, a window may have a particular six pixel row that
-contains too many changes (from black to white to black).  This will
-cause the printer to drop part of the line and possibly parts of the
-rest of the page.  The printer will flash the number `1' on its front
-panel when this problem occurs.  A possible solution to this problem
-is to increase the scale of the picture, or to split the picture onto
-two or more pages.  The second problem, ``page memory exceeded,''
-will occur if the picture contains too much black, or if the picture
-contains complex half-tones such as the background color of a
-display.  When this problem occurs the printer will automatically
-split the picture into two or more pages.  It may flash the number
-`5' on its from panel.  There is no easy solution to this problem.
-It will probably be necessary to either cut and paste, or to rework the
-application to produce a less complex picture.
