Data from the host computer is received either through the Centronics parallel port or the serial port. The gate array provides the control signals for DMA transfers from the parallel port to DRAM.
The serial port is designed primarily to interface to a Macintosh® computer. It has an eight pin
Due to the data flow speed limitations of using the serial interface with a Macintosh computer system ENCAD does not recommend using this port for production usage with the new printers. Hesitation may result if using this port and that can degrade the quality of the output print.
Possible solutions for the Macintosh computer user include using a print server device with an established network or installing a parallel port
The serial port is still required to download new firmware to the printer with a Macintosh computer.
The serial port is compatible with
The NovaJet 750 printer ships with a high speed print server that attaches to the parallal port for network compatibility.
