If you have been getting the -1096 error when printing under the PrintMonitor, it probably has something to do with your AppleTalk network setup.
Error -1096 is an AppleTalk ATP error that indicates the ATP sendRequest has failed because the retry count has been exceeded. This means that the workstation doing the printing is having a difficult time communicating with the LaserWriter or Print Server.
This suggests some type of AppleTalk network problem, which may be either physical or logical. Check the network for loose connections and proper topology. Also, AppleTalk traffic may be preventing the proper communication between the two devices.
