Quoting Sage Support pages:

Quarterly 941 Printing has been updated for the 2010 IRS changes to the 941 Form. The changes are only applicable to the Report Format ‘Entire Form’ and ‘Worksheet’ since the changes are in the text of the 941 Form. Also the year has changed on the ‘Entire Form’. The IRS has not made any changes to the Schedule B for 2010.

NOTE: The “Pre-printed Form” format has been designed based on the downloaded 941.pdf from the IRS website. If you use the “Pre-printed Form” format the alignment may need to be adjusted or the form may need to be modified.
