Hi,
To get output, you need the following:
Output type in config
Output type identified in Access Sequence in config
Output condition recorrd created in MN21
PID NDR = X assigned to users
PID ND9 = User group assigned in config (Only if you are using the Plant, Sloc, User group printer determination
Also, if the output type in config is set to "User Parameter, then it is looking for a default printer in the user's profile. If it is blank, then output will not print, regardless of config settings.
Use the T code NACE - output determination for all the documents.
