That you got it working from one station indicates that you've got the correct settings on the specification to get what you want.

The settings on the printer drivers of the 2 workstations may not be identical, even though the same driver is in use. There may be one or more settings different between the 2 drivers that is affecting the print margins.

There has to be something different because it kinworks in one place but not another. Another thing to look at is whether a workstation has 'Large Fonts' enabled via the Windows display settings. This has been known to adversely affect printing specifications, such as checks. This is a Windows setting that can be set in 1 or 2 places, depending on the version of Windows.
