Can you try this...
Open the Report in Preview
Click on 'Tools', 'Office Links' and then 'Publish with MS Word' this will create a RTF export of your Report.
If this has truncated some of your fields then you are not going to have any luck unless you are prepared to keep playing with the format of the access report so that it creates a better export to RTF i.e. Reducing Font Size and increasing the length of the fields being truncated. Because the export routine is pre-defined by Microsoft there is nothing else to play with.
There are known issues with lines being removed and formatting of long strings and memo fields being incorrect.
You could try Mail Merge to Word using code if Word is the Output required or PDF for accurate representation of the Access Report.
