In Step 4 on the Labels (or Product Labels) page, enter the Column you want to start and Row you want to start. As the on-page note explains, a 4x2 sheet has 2 columns and 5 rows, so starting at row 3, column 2 means the first label prints on the 5th position of the sheet. Sprwt inserts blank positions before your first label so the rest of the sheet is used normally. Leave both at 1 (the default) for a fresh sheet.
