Erika,
Since every site will have their own set of printers, you have to configure
"idt" to recognize the printers at your site. You do this through a file
called "ncarv_spool". If you look at the man page for "ncarv_spool"
it states the following:
The ncarv_spool file contains definitions for spooled devices to
be used by idt/ictrans. Each definition describes a rule used for
sending a set of metafile frames to a spooled device.
Each entry consists of a line of the form:
alias_name : translator_args : filter_chain
So, for example, if you have a PostScript printer that you normally
print to with the command "lpr -Plj145", then one line in your
"ncarv_spool" file might look like this:
PostScript : -d ps.color -simulatebg : | lpr -Plj145
The first entry "PostScript" is just your own alias name that you
choose. This is the name you will see when you click on the "Print"
button in "idt". The commands between the colons specify that you want
to convert your metafile to color PostScript and that you want to keep
the same background color as the metafile. The last part of the line
just sends the output to your printer.
You can have several lines in your "ncarv_spool" file, each one
specifying where you want the metafile output to go (it can be a
printer or a file). For example, if you want to send a particular frame
to an xwd file, you might have the following entry in your ncarv_spool file:
xwd_file : -d xwd : > gmeta.xwd
The "ncarv_spool" file can either go in the directory
"$NCARG_ROOT/lib/ncarg" so that all users of "idt" will be able to use
its entries, or you can rename the file ".ncarv_spool" and put it in
your home directory where only you will have access to the entries in
it.
For more information, do a man on "ncarv_spool" or "idt".
Cheers,
