    Simply brilliant

    Fantastic product and at a great price. Setup in 15 minutes, including installation and configuration on the PC. Printing 9.5 x 4 inch payslips using rear tractor feed. Print quality for a dot matrix is excellent and pretty fast. Cannot rate this highly enough, great value for money. Next day delivery was a blessing, too.
