Abstract

A printer driving system includes a printer driving control circuit arranged on an ink cassette carrying device of a printer, an inkjet print head cassette arranged on a supporting base of the ink cassette carrying device, and a connection port. The printer driving control circuit includes a driving signal coding chip connected to a bus wire. The inkjet print head cassette includes a driving signal decoding chip and an inkjet print head chip. The driving signal decoding chip is connected to the driving signal coding chip through the bus wire. The connection port is arranged on the bus wire connected between the driving signal coding chip and the driving signal decoding chip. The inkjet print head cassette is detachably arranged on the supporting base of the ink cassette carrying device of the printer through the connection port.

First claim

What is claimed is:

1. A printer driving system, adapted to be implemented on a printer, wherein the system comprises:
a printer driving control circuit arranged on an ink cassette carrying device of the printer and comprising a driving signal coding chip, wherein the driving signal coding chip is connected to a bus wire to output a driving signal;
an inkjet print head cassette arranged on a supporting base of the printer and comprises a driving signal decoding chip and an inkjet print head chip, wherein the driving signal decoding chip is connected to the driving signal coding chip of the printer driving control circuit through the bus wire, the driving signal coding chip provides the driving signal to the driving signal decoding chip to obtain a decoding signal, and the decoding signal is then outputted and received by the inkjet print head chip to perform an inkjet printing procedure;
a connection port arranged on the bus wire connected between the driving signal coding chip and the driving signal decoding chip;
wherein the inkjet print head cassette is detachably arranged on the supporting base of the printer through the connection port;
wherein the connection port is a busbar connector comprising a first connection terminal and a second connection terminal; the first connection terminal is connected to the bus wire to which the driving signal coding chip is connected, and the second connection terminal is connected to the bus wire to which the driving signal decoding chip is connected; the first connection terminal and the second connection terminal are connected with each other; and
wherein the first connection terminal or the second terminal is a male terminal, and the male terminal is extended parallel to a horizontal plane.

2. The printer driving system according to claim 1 , wherein the driving signal is a driving signal pulse, a driving signal data, a power ground signal, or a power signal.

3. The printer driving system according to claim 1 , wherein the first connection terminal is a male terminal, and the second connection terminal is a female terminal.

4. The printer driving system according to claim 1 , wherein the first connection terminal is a female terminal, and the second connection terminal is a male terminal.
