GHOSTSCRIPT -> HLLIP -> HP OfficeJet Pro 8600

     I am plotting using gnuplot which puts out postscript
which will not print on an HP86xx printer.

     I am trying to get ghostscript to work with hplip to put
out the proper format, and having  LOT of difficulty.

     Here is the code that HP tells me to use and the errors
that follow.

     Can someone tell me what the two errors means, and perhaps what
the correct model name for the printer is?

     What file is it trying to open, and what is 'initial device'.

     Thanks in advance, Homer W. Smith

/tmp/data.print
