problem in printer which connected to the digvis of AC800F.......
Goto Configure tool, All Programs > ABB Industrial IT > Freelance 2013/Vxy > Configure. one window will popup. There click on printer settings.
two type of printers can be configured
Printer 1 - by default it is configured for hardcopy
Printer 2 - by default it is configured for alarm and event(dotmatrixs one)
So catch here is in your case which ever is not selected in hardcopy printer, make it <no printer> and then it will stop printing alarms and events. But this action will stop all alarms and events to be printed.check image below
If you do not want to stop all AnE then go for manual printing option so that it will not print automatically all but will print selected page which ever operator want to print, check at SSL1 or SSLN level settings in that case keep printer1 and printer2 selected as it is. check image below
Check related details in online help, hope that helps
