Years ago when I was selling printers, most of the distributors would slap a UPS label on each printer box and ship them out.For example, if you ordered 12 printers, you'd get 12 separate packages, and 12 times the opportunity for one to be damage or lost during shipment.
One distributor, however, would drop the printers into a large box, and would ship 3 or 4 at time. The results was cost savings and efficiency.
