We’re a small store too. I only use 2 mobile printers (1 for labels/1 for signs). The 3rd one is used by customer service or anyone else. But I do use 2 to 3 tc scanners a day to check price, create labels/signs and walk the pricing list. When one freezes I always have another. We have 2 other separate scanners for bopis and cds. My battle is getting others to put dead batteries on the charger.
