Sony UP-X898MD >>> Sony UP-X899MD

Both the Sony UP-X899MD and UP-X898MD printers are *hybrid* (analog/digital) A6-format models. Both printers are designed for ultrasound diagnostics and compact clinical use.
The Sony UP-X899MD is an updated version of the previous UP-X898MD model, offering a number of significant technical improvements.
Key differences between the Sony UP-X898MD and UP-X899MD - what has changed :
* Performance: The UP-X899MD delivers improved, faster print speeds and exceptional image quality.
* Ergonomics and Design: The UP-X899MD features a new, improved user interface that offers a new level of convenience and intuitive control.
* Advanced dual cutter: The dual cutter in the Sony UP-X899MD model can significantly improve workflow efficiency by allowing prints to be trimmed from the top or bottom. This improvement is made possible by the presence of blades at the top and bottom of the output slot. Smooth downward cutting is possible even when the printer is installed under an ultrasonic console.
* Connectivity: Although both models feature analog (BNC) and digital (USB) inputs, the UP-X899MD stands out specifically for its support of USB Type-C and its superior integration into modern setups.
