SNAP Retrofit memory resident devices are internal and external non-volatile, re-programmable devices that store electronic forms, checks, signatures, logos, fonts and graphics for secure, reliable and fast laser print output.

External devices contain easily removable cards that allow lock up for physical security. Internal devices plug in to a laser printer's font cartridge or standard memory expansion slot. If the device is not physically present, images such as checks and signatures will not print.

SNAP Retrofit devices are available in a "custom or personalized" manner. You can supply the resources to put on a device or they can be produced to your specifications by Synapsis' Forms Service Center. Synapsis continues to release new SNAP Retrofit devices which keep pace with the introduction of new laser printer families. Newer versions automatically configure to the IP address of the printer and support 10 and 100 Mbps, full and half duplex as well as versions that have built in bar code fonts.
