I recently worked with an organization that configured an OSA-ICC TN3270E 
printer session, and it makes sense for them. They did this because one of 
the TCP/IP products available for z/VSE, the one they use, includes a 
TN3270E server that is limited to display terminal sessions and does not 
support printer sessions. This particular organization uses the TCP/IP 
product's TN3270E server for display sessions, but they also have a line 
printer they need to continue running. Previously, historically, the line 
printer was coax attached to an IBM 3174 Establishment Controller. The 
same line printer is now connected via OSA-ICC's TN3270E server and 
continues to behave like a terminal-attached printer, with IBM Personal 
Communications in the middle handling the emulation. Direct would have 
been nice, and technically the printer can directly connect via a TN3270E 
printer session (it has a built-in TN3270E client), but for some weird 
reason when the line printer operates using a different connection it 
unavoidably changes "personalities" and won't interpret the same data 
stream the same way. That's how the printer is designed, not something 
that can be changed. So rather than reconfigure z/VSE's output to adjust 
the print data stream, they inserted IBM Personal Communications in the 
middle to accept the original data stream then handle some very light 
reformatting before passing it on to the printer via LPR/LPD protocol. 
This arrangement works!
