Printing all receipt labels (Mass Print)

I have just went through changing our receiving label report to be able to print on our Zebra label printer without barcodes or unnecessary fields that we do not need. The receipt labels are able to print one by one. For some reason, when I select the “Print All” checkbox on the print dialogue, only the first line prints. If I were to select each line separately I can print them one at a time, but the print all does not work.

Does anyone have any ideas on why this is happening?

Thanks in advance,
Jakob
