Datamax-O'Neil E-Class Mark II Accessories

Datamax-O'Neil E-Class Mark II Popular Applications

Manufacturers use E-Class printers for applications throughout their product lines and storage facilities. Many manufacturers demand high grade, durable labels and tags that normally require a very high-end printer; however the E-Class, a lower cost printer, has the capability to print on the toughest materials including synthetic serial labels, large “work in progress” labels, durable product labels, thick bin tags and shelf marking tags.
The healthcare industry is rapidly adapting auto-ID technology across many applications. Healthcare providers need printers that can be network shared, remotely managed, and versatile for use in many applications. The E-Class is ideal because it meets all these needs plus it can be easily updated for changes in technology. The E-Class’ small size also makes it a perfect fit for printing patient identification wristbands, laboratory specimen identification labels, records labels, and prescription labels
  In-Store Retail
Retail barcoding is more than just scanning an item at checkout. It follows a complete cycle, and starts when the product is received, stocked, displayed, sold, returned, and prepared for resale or return to manufacturer. The small size and versatility of the E-Class make it the ideal solution for generating item labels and shelf tags at every stage of the retail sales process.
The parcel and postal industries place continuous demand on their printers for printing primarily direct thermal labels and tags. The E-Class’ small size, optional cutter, and reliability makes it an ideal fit for printing postage labels, tote/tray tags, and bag tags. Because the printer’s firmware can be updated, it adapts easily into barcode technology updates that increase efficiency and accuracy.
  Transportation & Logistics
The transportation and logistics industries use the E-Class in their distribution centers and warehousing facilities for labeling and tracking shipments. These facilities are exposed to extreme changes in the environment and the label printing capability is essential to the operation. The E-Class is ideal for printing shipping labels continuously, large rack labels, and mobile pick slips in extreme conditions. Plus the small size, networking capability and low cost make it a good choice for redundant printing capabilities
