I also just located this information that might help you if the form you're looking for is on this page.

Jim Burcicki provided this answer to another student:
The workbook pages are best printed on 11"x14" sheets of paper using landscape orientation. Also, some of the forms such as worksheets "wrap around" to take up two pages because the forms do not fit on one page.
As an FYI...
Go out to the Student Community under the Business Group. On the left hand side, there is a section called Financial Accounting. In there, there are additional blank forms and supplemental videos.
