The L4360 and ET-16605 share colour printing, automatic duplex printing, Wi-Fi and Wi-Fi Direct. Their confirmed differences are set out below.
ET-16605 supports an automatic document feeder; L4360 explicitly does not; ET-16605 supports automatic duplex scanning; L4360 explicitly does not; ET-16605 lists a maximum paper size of A3+, versus A4 / Letter on L4360; Included black ink yield is listed at 6600 versus 4500 pages for L4360 and ET-16605; L4360 weighs 5.2 versus 20.7 kg for ET-16605.
The L4360 may suit a need for higher stated included-black yield, while the ET-16605 may suit someone prioritising feeding multiple pages for scanning. Consider the actual functions, throughput, and paper format required. An entry supplied for just one model is insufficient to conclude that the other lacks the feature.
