Tally Dascom LA550W Matrix Printer



Up to 500 cps


The dependable LA550N and LA550W offer class-leading performance. Flat push tractors drive forms through a straight paper path, resulting in delivery of invoices, shipping bills, labels, and statements time after time. At up to 750 characters per second and with workloads to 26,000 pages per month, the LA550N and LA550W are ideal for tough, transaction printing. The LA550N and LA550W can be optionally configured with up to three input tractors.

From the small 80-column footprint of the LA550N to the 136-column capacity of the LA550W, their rugged design and quiet operation equip them for the warehouse, the shipping dock or the front desk. Back room durability combined with front-office 24-wire print quality and a variety of automated performance features make the LA550N and LA550W a serious solution for demand document pricing.
