We are running two Intel macs and 2 ppc macs. We have alway had a problem with the intel mac that we use as a working server, which simply won't print to the DesignJet 800 plotter. If you send a print file it just disapears. We've re-installed Vectorwork multiple times. Even making .pdf files and printing those, the files rarely come out clean (they don't rotate and sometimes crash the plotter.) The other 3 computers all worked fine, but this morning the server crashed and froze the other Intel mac in the middle of trying to print a file. On re-starting everything, all of the DesignJet preferences are gone from the Intel mac (papersizes, etc. although it still shows the printer.) Suggestions?
