No, I don't know what 6.0.10 did for anything. It certainly didn't help with TSP printing. AC is simply unable to format scripts based on the TSP drivers.
I would recommend giving making the drivers the default driver. Try on every computer. This is how we solved the problem.
Found computer that could print to TSP using driver as default.
Shared that print driver to all other printers.
Made those print drivers default as well.
Works perfectly. Not the best scenario as now the normal default printer has to be chosen each time.
