This is a thermal printer like you would find on a cash register or adding machine. It will print simple strings passed to it via TTL serial, bitmap images (poorly) and it can generate several different formats of barcodes.
The IRF3710 MOSFET is a Field Effect Transistor has a drain voltage of 100V, gate voltage of 20V and drain current of 57A. A MOSFET is an abbreviation for Metal Oxide Semiconductor Field Effect Transistor TO-220 Package.
The DAC0808LCN is an 8-bit monolithic digital-to-analog converter (DAC), It will interface directly with popular TTL, DTL or CMOS logic levels, and is a direct replacement for the MC1508/MC1408. For higher speed applications.
