I've done it both ways and
printed all my labels at once no problem.
OK, that's a good start, as it suggests that you managed to print what you
expected...
After that you have the option to
save the document which I did.
....but I wonder if you saved he thing you really needed to save at this
point.
Apologies in advance if all this is familiar to you...
When you merge, you start with a "Mail Merge Main Document" that contains a
number of merge fields.
You connect to your "Mail Merge Data Source", and perform the merge,
If you merge to a new document, the new document should contain all the
merged data as at the time you did
the merge. That document is no longer connected to tyour "Mail Merge Data
Source", and if you save it, re-open it and reprint it, it should be
unchanged.
Suppose you save your "Mail Merge Main Document"
Then you change your data source.
Then you reopen your "Mail Merge Main Document". What you see when you
preview or merge should reflect the current content of your mail merge data
source.
I lost track after that, which may suggest that we could be seeing things
from completely different perspectives - if so, have a look through what I
said and see if you can see where my understanding diverges from yours.
