Hi.
We suspect you may observe a bug. I will try possibly repeat it.
Can you please check one thing - if on Printing form or in Printing parameters they have checkbox Printing dialogue = ON.
This is not the issue of upgrade SERP. But serverip.dat in this case contains the value: 192.168.88.12:1301, so this is local IP of the server with SERP.
Anyway I don't understand what do you me...
