There are three indicators to measure the quality of a printer: print resolution, print speed and noise. There are many types of printers. According to whether the printing element has an impact action on the paper, they are divided into impact printers and non-impact printers. According to the structure of printed characters, they are divided into full-width character printers and dot matrix character printers. According to the way a line of characters is formed on paper, they are divided into serial printers and line printers. According to the technology used, there are cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, light-emitting diode and other printers.

The movable plate 10 is symmetrically provided with round holes for the guide rod 11 to slide through. The spring 19 is sleeved on the outer side of the guide rod 11 and is located between the movable plate 10 and the inner wall of the cavity 9. The spring 19 provides elastic force to push the movable plate 10 backward along the guide rod 11, so that the first wedge block 16 and the second wedge block 17 are always in contact.

[0037] Step 2: file reception, receiving the printing information through the second computer host 3, and sending the printing information to the printer body 1;

[0038] Step 3: File printing, information printing through the printer body 1.

[0039] When the first computer host 2 is operated in step 1, the control connector 7 always keeps the second data line 5 and the third data line 6 in a disconnected state.

The starting module is electrically connected to the motor 14.

[0042] The working principle of the present invention is:

[0043] When in use, the printing information is downloaded or imported through the first computer host 2. At this time, the first computer host 2 sends the printing information to the second computer host 3 through the connecting line. At this time, the second data line 5 and the third data line 6 are separated by the control connector 7, and the data is in an unsent state. At this time, the data is received by the second computer host 3, and the starting module controls the motor 14 to work. The motor 14 drives the threaded rod 15 to rotate, and the threaded rod 15 drives the second wedge block 17 to slide along the slide rail 18, so that the hypotenuse of the second wedge block 17 squeezes the first wedge block 16.

At this time, the second computer host 3 receives the print file. During the receiving process, the file monitoring module monitors the receiving situation. When the receiving is completed, the disconnection module controls the motor 14 to work in reverse, disconnects the contact between the first conductive contact 12 and the second conductive contact, so that the connecting line is disconnected. At this time, the second computer host 3 controls the printer body 1 to print.
