   I've modified the lp interface file before by adding the same 'NR'
   command and it worked for me.  Another feature I added was to select a
   pen that would correspond to the size of paper that had to be loaded
   next (ie: pen 1 A size, pen 2 = B size etc..), this would allow the
   operator to look at the front panel to determine what size of paper
   to load (the paper size was derived from the first character of the
   file name).  I don't have the script anymore but the modifications were 
   only a few lines of borne/korn shell commands.  I didn't get any of 
   the error messages you are referring to.

   The difference is that I used the RS-232 I/F.  I didn't get any
   messages, the plotter would just 'XOFF' the computer until the user
   changed the paper and pressed remote.  I suspect that HP-IB doesn't 
   have an XOFF equivalent.

   HP's ME10/30 products include a plot spooler (doesn't use the lp
   spooler) for complete control of what drawings get printed and when.
