Currently the default label + packing slip settings are very misleading when used in conjunction with batch level printing options.
It is expected that a default setting would be pre-selected when viewing batch level print options. Example; My default is set to label + packing slips, however this is not preselected when selecting print all, I then select print all with labels and packing slips and I get double packing slips.
Related to the above example, the batch level print options would be expected to override print settings not have an additive effect.
The labels + packing slips setting when printing in batches differs in functionality from the one set in settings. Example: When chosen in settings, labels and packing slips are printed one after another. When chosen in batch printing, all labels print, then all packing slips.
