In addition to its industry-leading printer and LCD businesses, Seiko Epson is renowned for quality precision instruments including clocks for diverse applications ranging from watches to computers and wireless communications devices.  “This is an excellent endorsement of the MMP Portfolio,” said Mac Leckrone, Alliacense president.
