Canh,
The frx file of each report is a dbf. Open the file, "use reportname.frx". You will be able to see the fields expr, tag and tag2 field.
In the expr field, you will be able to see the printer settings. As these settings may not suit the other PCs, it is best to remove them completely. The associated information in the tag and tag2 field needs to be removed as well.
HTH
Yau
