This is something new that has come up. About 25% of the times I try to plot a file, nothing plots and nothing appears in the GSPQUEUE window. When I look at the QUEUE folder, the files there are, for example, GP440700.PRM AND PG440700.TMP, instead of GP440700.GSP. If I simply rename the file extension to .GSP the job will cut. The GSP.NET file is there. This only seems to happen when plotting over the network, and not from the computer where the plotter is physically attached. And it doesn't matter which of the 2 plotters we use or which of 4 workstations, it happens in both QUEUE folders. I'm stumped on this one. Any ideas?
