A method and apparatus for delivering solvent free marking material to a receiver is provided. A printhead includes a discharge device having an inlet and an outlet with a portion of the discharge device defining a delivery path. An actuating mechanism is moveably positioned along the delivery path. A material selection device has an inlet and an outlet with the outlet of the material selection device being connected in fluid communication to the inlet of the discharge device. The inlet of the material selection device is adapted to be connected to a pressurized source of a thermodynamically stable mixture of a fluid and a marking material, wherein the fluid is in a gaseous state at a location beyond the outlet of the discharge device.

Method and apparatus for printing

A method and apparatus for printing and coating includes providing a pressurized source of a thermodynamically stable mixture of a solvent and a marking material. A printhead is connected to the pressurized source. The printhead is configured to produce a first shaped beam of the marking material and a second shaped beam of the marking material. The marking material can be different marking materials or the same marking material.

An apparatus and method of delivering a functional material is provided. The apparatus includes a pressurized source of fluid in a thermodynamically stable mixture with a functional material. A discharge device having an inlet and an outlet is connected to the pressurized source at the inlet. The discharge device is shaped to produce a collimated beam of functional material, where the fluid is in a gaseous state at a location before or beyond the outlet of the discharge device. A beam control device is positioned proximate to the outlet of the discharge device such that the collimated beam of functional material is controlled after the collimated beam of functional material moves through the outlet of the discharge device.

A method and apparatus for delivering a functional material to a receiver includes a pressurized source of solvent in a thermodynamically stable mixture with a functional material. The solvent is in a liquid state within the pressurized source. A discharge device having an inlet and an outlet is connected to the pressurized source at the inlet such that the thermodynamically stable mixture is ejected from the outlet. A receiver having a back is positioned a predetermined distance from the outlet of the discharge device. The solvent of the thermodynamically mixture evaporates at a location beyond the outlet of the discharge device and a predetermined amount of the functional material contacts the receiver at a predetermined distance from the back of the receiver.

A molded article containing an electrical element buried therein has at least two leads, and portions of the leads are left exposed. The article is improved in that all of the leads are left confined within the confines of the article, the exposed portions of the leads being disposed within at least one aperture through the article. Also a molding process for making the article useful as a catcher plate for an ink jet printer. Broadly, the process comprises the steps of placing the portions of the leads to be exposed, each in a groove in a post that is part of the mold, and closing the mold cavity with a closure plate containing an elastomeric material aligned with the post and leads, such elastomeric material having a coefficient of thermal expansion that is greater than that of the material used to make the mold.
