The VideoJet driver, in its extended mode, uses row and column numbers to locate field data within the print message format.

The XL print driver allowed for 3 rows and 4 columns but the Eclipse driver allows 4 row values 0-3 and 5 column values 0-4.

The XL protects its array bounds by converting any index with a range error to 1.

Rondo was trying to use 5 columns. Since a bug with logo printing in SCN 4304 is also being fixed, an additional column is also being added in the same release. To avoid having to change and release Eclipse as well to allow them to use the 5th column, the XL driver will now stop converting column 0 to column 1. This effectively changes the column index field from a 1 based index to a zero based index.
