Epson EcoTank L6191 Printer vs Epson EcoTank L6550 Printer — choose by the use case in the table (role/paper, document features, connectivity, speed).
When to pick which:
Pick Epson EcoTank L6191 Printer if you need: automatic duplex, higher ink yield, ADF or clearer scan/copy in the table.
Pick Epson EcoTank L6550 Printer if you need: automatic duplex.
10×15 cm photos: EcoTank L6550 about 43 seconds and EcoTank L6191 about 69 seconds in published figures (~26 second gap). That edge is conditional on matching quality mode, bordered printing, and test conditions — paper type alone is not enough.
Key differences:
Based on the specs table, Epson EcoTank L6550 Printer fits most office needs better thanks to: Iso Duplex Print Speed Black: 6.5 vs 16; Iso Duplex Print Speed Color: 4.5 vs 9; Automatic Document Feeder Capacity: 30 vs 50.
Maximum dpi and ink bottle series numbers alone do not settle the buy.
Adf Supported Paper Weight: 64-95, Ethernet Connectivity: 1, Ink System: Black, Cyan, Magenta, Yellow, Interfaces: Hi-Speed USB 2.0, Wi-Fi, Wi-Fi Direct, Ethernet, Print Colors: 4

Not by themselves. Dpi alone does not prove higher quality, and bottle series is a consumables difference. Decide by role, duplex/ADF, speed, connectivity, and price.
