Return code from RP.EXE ?

I am calling rp.exe from within a program, to print a postscript file the program generates. Sometimes although the program has done all the right steps, the print just never appears. I suspect rp.exe is getting an error from the printer, but if so how do I trap this? Is there a return code?

Thanks - good product!

There is a return code, 0 if it works OK, 4 if there is an exception of some kind.

Generally there isn't much to go wrong, the spooler should accept the job whether the printer is ready or not.
