To setup your default TID printer, open a mainframe session and go to the COM-PASS screen. (The COM-PASS screen is the home screen once you logged into the mainframe) Enter *UDEF
The UDEF window is where you will enter your printer information. Tab to the Printer field and enter your TID printer # ( I used 2475 as my TID printer in this example).
Next, hit F5 or PF5 to update your printer setting. The Printer will revert to UTX2475P and now your default printer is setup.
