On my ativa at-lp 1000 label maker, I get message Data Error when I try to print It won't print

1) I can't find anything about this label printer online other than a picutre and that it was sold by both Staples and Office Depot. Without the user manual for guidance, one simply does not know what keys will generate the labeling you wish. What ever paramenters have been set c.annot accept your following input. For instance if a you had a margin of five inches and the print paper was only 3 inches, you likely would have an error message generated when you entered enough data for 5 inches. (This is a two line printer so I really don't know if it has a wrap around function or not, i. e. wrapping the extra length of text to the next line). In other words, your instruction set to the printer is such that whatever text you are entering is not permitting by the instruction set. You badly need the manual.
