lines and objects drift down (vertically) when printing on continuous media
Printing on long continuous media we are seeing the objects (lines, shapes) drift vertically from their location as designed in Bartender. The longer the label printed, the further the drift - always (resulting print) dropping the objects lower than intended. This happens on both individual objects and underlined text - for example, on a label approx 13-14 inches long, the objects start to drift downward getting noticably offset by 1/4" or so, with greater drift on longer labeling.
Any insight on how to mitigate this? We have tried to spool the entire print (that has helped with other issues - but not the drift) or make the label as compact as possible (reduce length) or print rotated 180 degrees, but so far we can only reduce the drift slightly - not eliminate it. The tags are printed with legal text, folded over and stitched into product, hence the needed length.

The first thing I would check in this situation is that the label dimensions and configuration in BarTender is correct. A 1mm error in the label length for example will become very apparent quite quickly in a print run

Label dimensions are correct - width and cut length, and we are using several files at different lengths that consistently have this problem. This is continuous media, not set length labels. Only the lines, shapes drift - all text prints placed as expected, but the objects will drift down (worse drift when there are more of them used in the design and when the cut length is longer) sometimes enough to intersect with the text.

Very odd if the text is staying in the correct place. Are you using the Seagull rather than ZDesigner driver? If not I would suggest trying it with that as I have found in the past that these work far better.

Yes - confirming printer is using a cab SQUIX driver copyright Seagull Scientific.

Oh yes Cab Squix not Zebra, I see you have amended that now!
By default BarTender will create the graphical elements and send them down to the printer as an image and store it in the volatile memory usually at the start of the label file being sent to the print. Each label in the batch will then include a recall and print the graphic command and I wonder if something is going wrong with this process.
You could try adjusting some of the performance and especially the caching options on the File>Print screen and see what this does. It may slow down the label download process as if the graphics are not cached they will be sent down with each label.

Thank you - I did check this in the past and I have the settings as your image above (allow static graphics) thinking it might help - but it didn't eliminate the problem.

Have you tried turning these options off, especially the top one?
