Since we only have three or four applications that will do this I don't believe it will be difficult to customize the program that does the checking. The problem is I can't find any information on lpd or lpr that I can use to help me create the filter. The intent is to check the file on the local machine and then send it to the remote machine were it will be printed. We are currently running SunOS 4.1.2. Any help is appreciated.
