ORLANDO, FL – May 11, 2010 - Datamax-O’Neil, part of Dover Corporation’s (NYSE: DOV) Product Identification Platform and global provider of label and receipt printing solutions, announces that it has integrated the former Extech Apex and S2000i printers into its printer portfolio, and the rebranded printers are now available to the company’s worldwide partner network. The Apex and S2000i printers expand the range of applications where the company’s mobile printers have been successful and will provide new opportunities for growth in the increasingly mobile global workforce. “The Apex and S2000i printers bring tremendous diversity into the Datamax-O’Neil portable printer family and will expand our ability to sell products in applications where our existing line might not have been the perfect fit,” said Paul Lehmann, director of product management for Datamax-O’Neil. “The existing Datamax-O’Neil portables are known throughout for their industry-leading rugged reliability, and the Apex and S2000i printers bring a value element that will appeal to customers that demand ease of operation, reliability and low cost, but don’t require the extremely rugged characteristics needed forcertain applications.”
