A portable printer for printing on a roll of paper or label stock is provided having automatic print alignment with the width of the roll. The portable printer has a housing having a compartment for receiving the roll, a cover to access the roll, and a centering mechanism for the roll. The centering mechanism has two rotatable spindle members in the compartment engageable with the opposing ends of the roll's tubular core, and a pair of racks each coupled to one of the spindle members, and to each other by a gear, to enable each of the spindle members to move in opposite directions with respect to a center between the spindle members. The position of centering mechanism is optically, magnetically, or electro-mechanically encoded and a sensor reads the encoded position of the centering mechanism. A controller automatically aligns printing with respect to the roll's width in accordance with the encoded position read by the sensor, thereby preventing printing outside the width of the paper from the roll. The centering mechanism may be locked when the cover is closed to prevent movement of the gear, and the spindle members and racks coupled thereto. A removable RF communication module may be provided in the printer to enable communication with a host terminal or computer system.

The invention relates to a dry valve assembly with a quick joint, which consists of a male joint part with a valve and a female joint part with a valve, wherein the male joint part consists of a manual valve, a quick joint and a lock pin in starting and shutoff linkage with the valve; the female joint part consists of a valve capable of elastic automatic recovering and shutoff; and a pin hole matched with the lock pin on the male joint is formed in the female joint, the rotation of a valve rod drives the lock pin to move, so as to ensure that the quick joint is mounted in place and unified with the opening of the valve, and ensure the safety of the operation. The dry valve assembly overcomes the safety hazards of high possibility of mal-operation and fluid leakage due to the lack of effective safety protection design in the quick butt jointing and transferring operation of the fluid medium in the prior art. By adopting the design, the valve can't be opened when the quick joint is not yet butt jointed; the quick joint can't be cut off when the valve is not yet completely closed; and after the quick joint is disassembled, the leakage problem of the residual fluid medium at the joint is avoided. The design not only realizes the quick connection problem that the pipelines need to be frequently connected, but also ensures the safety of the joint of the transfer pipeline of toxic, inflammable and high-corrosive medium.
