Thanks for all the help, all of you! It's great to have such a wonderful resource for this specific type of information.
I fixed the trunk issue--no problems. Every phone can now dial out. Still having trouble with the TAFAS. I enabled it in the system, but not sure what the next step is. I'll go through the manual again and see if there's anything I missed.
As for the printer, my cable from the SX--50 to the printer are both 25-pair ends. The one at the printer is the D-shaped 25 pin as well and has the two metal tabs that snap over each end to keep it secure. The printer book says it accepts both serial and parallel connections.
I tried a data dump from the console. Now from what I can see, I should have info printing at the default setting, right? I did enable the things that TECHarry recommended, however I still have no printing at all. I can run the diagnostics through the printer itself and it all comes out fine (test pages, setttings printout, etc).
Any thoughts on this?
