Scripting printing in 8.5

[Ultradistance2005]

I seem to have a problem. I have three different printers that we use in the office, each with a different type of media. I have scripts set up to print to those specific machines for specific tasks. I run 8.5 on all the machines, with our server running the Server version. All was well, until a few days ago. Now none of the scripts will call up the correct printers, or if they do, it is only on certain computers. I've had to insert dialogue boxes to allow users to fix the printer.

Any reason why this should become so unstable? I've tried rebuilding the scripts with no luck.

Any help would be appreciated. Thanks,
