When trying to generate a Datamatrix barcode that will fit in a small area on the label the Datamatrix barcode stops printing on the label. During label development Symbol Size Auto was used first. This caused Datamatrix barcode to print too large. The fixed Datamatrix symbol sizes were tried to better size the Datamatrix barcode. The (M1156) An Error occured drawing the symbol popup is displayed. At this point the Datamatrix barcode stopped printing on the label.
Solution 1) Change the Symbol size back to Auto and reduce the cell size of the Datamatrix barcode to suit your size requirements.
Solution 2) Change the Symbol size large enough to handle the data and reduce the cell size of the Datamatrix barcode to suit your size requirements.
