A connector system for protecting the transmission of signals from and/or to a tool in a high pressure environment. The system includes a connector through which a signal transmission line, such as an electrical cable or optical fiber extends. The connector is coupled to a protective tube, and includes an internal chamber in communication with the interior of the tube. A fluid, such as a liquid, is disposed within the connector and the tubing at a pressure higher than the environmental pressure. In the event of a leak at, for instance, the connector, the high pressure fluid flows outwardly rather than allowing the inflow of deleterious fluid from the environment.

An ink jet printing apparatus as claimed in claim 5, wherein black ink has a permeation property of a Ka value less than 1 ml m-2msec-2to the ordinary paper. 10. An ink jet printing apparatus as claimed in claim 5, wherein black ink contains a pigment. 11. An ink jet printing apparatus as claimed in claim 5, wherein the ordinary paper printing mode executes printing based on ink droplets of a predetermined size and the high speed absorption paper printing mode executes printing based on ink droplets of a size smaller than the predetermined size. 12. An ink jet printing apparatus as claimed in claim 11, further comprising a printing head that can eject the same ink as a large droplet and a small droplet. 13. An ink jet printing apparatus, wherein an ink ejection amount per one pixel is 2.8×10-3pl/μm2-8.4×10-3pl/μm2onto a printing medium having a permeability of 5 ml m-2msec-1/2or more as a Ka value in a case of using ink having a permeation property of 1 ml m-2msec-1/2or less as a Ka value for PPC paper. 14. An ink jet printing apparatus as claimed in claim 13, wherein the ink ejection amount per one pixel of color ink is 2.2×10-3pl/μm2-5.6×10-3pl/μm2onto the printing medium. 15. An ink jet printing apparatus that performs printing by ejecting ink to a printing medium, wherein an ink ejection amount per one pixel is 2.8×10-3pl/μm2-8.4×10-3pl/μm2onto a printing medium that contains substantially no sizing agent but contains alumina particles. 16. An ink jet printing method, which performs printing by executing relative movement of a printing head to a printing medium and ejecting at least ink from the printing head during the relative movement, performing printing in a printing mode selected from a plurality of printing modes which correspond to different printing mediums and have different relative movement speeds of the printing head to the printing medium, respectively, said method comprising the step of: controlling the printing head to execute ejection in a manner that for a printing mode having a high relative movement speed, an ink ejection amount per one pixel is made smaller than that in a printing mode having a lower relative movement speed than the high relative movement speed, and that for the printing mode having the high relative movement speed, ink and a processing liquid that makes the ink insoluble are ejected. 17. An ink jet printing method as claimed in claim 16, wherein the printing mode having the high relative movement speed is used with a printing medium that contains substantially no sizing agent but contains alumina particles. 18. An ink jet printing method as claimed in claim 16, wherein the printing mode having the high relative movement speed is used with a printing medium having a permeability of 5 ml m-2msec-1/2or more as a Ka value in a case of using ink having a permeation property of 1 ml m-2msec-1/2or less as a Ka value for PPC paper. 19. An ink jet printing method as claimed in claim 16, wherein said printing step is performed with a printing head that utilizes thermal energy and forms bubbles in the ink to eject the ink by pressure of the bubbles. 20. An ink jet printing method, comprising: a printing step for executing a high speed absorption paper printing mode for use with a high speed absorption paper, which contains substantially no sizing agent but contains alumina particles or which has a permeability of 5 ml m-2msec-1/2or more as a Ka value in a case of using ink having a permeation property of 1 ml m-2msec-1/2or less as a Ka value for PPC paper, and an ordinary paper printing mode for use with ordinary paper, respectively, as the printing mode,
