wholesale printers

Do you know where to buy cheap but good quality wholesale printers? My past company is in need of them since they're aggressively opening lots of stores which need printers. They need to strike a good deal so they can save on cost but not sacrifice the quality. They wouldn't want to buy cheap printers which would conk out on them every so often. The money they saved up may just be used up having those printers repaired. So they also need to make sure that they have good after sales support
