If, when starting plotconfig, an error saying something about libCDSXmotif appears, set the following environment variable.

setenv LD_LIBRARY_PATH ${ICHOME}/tools/lib

Had a problem only printing A-size plots, no matter which printer was used.  The plot would go to the correct printer, but it would print the incorrect size.

The file with all the information about plotting is in ${CDSHOME}/tools/plot/.cdsplotinit.  This file is created/edited with the plotconfig command which is located in ${CDSHOME}/tools/plot/bin.

Our problem had to do with how the queues were set up in plotconfig.  They should be set as follows:

B size on edg1:  lpr -Pedg1 -oPageSize=11×17

B size on plotter:  lpr -Pplotter -oPageSize=Tabloid

C size on plotter:  lpr -Pplotter -oPageSize=16×20

D size on plotter:  lpr -Pplotter -oPageSize=22×30

Note that 16×20 is not the real size for ansiC (17×22), nor is 22×30 the size for ansiD (22×34).  I had to pick sizes that were available in the ppd file for the plotter.  This file is in /etc/cups/ppd/plotter.  This is also the reason that B size on edg1 uses 11×17, while B size on the plotter uses Tabloid.
