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.

A portable data collection device is provided for reading fluorescent indicia, such as barcodes. The device includes a housing with a pivotable image capture module. The image capture module includes an adjustable aperture, a color detector array for imaging light received through the aperture, and a removable flash module to provide ultraviolet light. Optics in the image capture module focus the light received through the aperture onto the detector array, in which the detector array is movable with respect to the lens to provide proper focus of an image onto the detector array. The adjustable aperture has an iris wheel to control the amount of light received by the detector array. A programmed controller is provided in the housing which operates responsive to a user interface to image and decode indicia, or capture color digital images in memory. A display on the housing shows images received by the detector array in a non-fluorescent imaging mode to target indicia to be imaged and decoded, where the controller automatically adjusts the focus of the image by adjusting the focal distance between the detector array and the lens. In response to user actuation via the user interface, the controller energizes the flash module to emit light, including the excitation wavelength(s), which enable the indicia to fluoresce, and the detector array receives fluorescent light to capture an image frame of the indicia. The duration of the flash is in accordance with the amount of light measured by a light sensor in the image capture module. The indicia in the image frame is then decoded by the controller to provide data representative of the indicia.

A label printer feeds stock having peelable labels or without peelable labels fed by a platen roller against which a print head bears. A bail carrying a bail roller which is latchable in two positions, is provided. In one of these positions, the bail roller is away from the stock so that the stock is fed over a peeler bar, and in the other of the positions, the bail roller wraps the stock around the peeler bar. The latter position is used when the stock has peelable labels and is so called &ldquo;linered&rdquo; stock. The print head can print directly on the stock, and the stock having the printed labels is then fed out of the printer. In the second position, the labels are peeled off the stock as it travels around the peeler bar and can be removed by the user while the liner from which the labels have been peeled leaves the printer. No rethreading of stock is required to handle different types of stock, thereby increasing the flexibility and simplifying the operation of the label printer.

Label printer which handles label stock with and without peelable labels

A thermal label printer includes an actuation mechanism and follower for facilitating loading of stock (e.g., label stock). A pivotable printer head pressure plate includes the actuation mechanism which cooperates with the follower coupled to a peeler roller. As the pressure plate is moved from a closed position proximate a platen to an open position for loading of stock or for cleaning the printer head, the peeler roller is automatically translated from the platen. The resulting roller gap and displaced printer head provide unrestricted access for threading of the printer. The printer also includes a programmable device in the printer electronics for reconfiguring the printer to accommodate a variety of thermal print mechanisms.

Thermal printer

A printer has a computer system which stores and uses multiple application programs. The printer may be a label printer which includes a printing mechanism, and a computer for controlling the printer mechanism and the advancement of label stock for the printer mechanism to print labels on the label stock. Coupled to the printer may be a barcode scanner controllable by the computer. The system includes a memory accessible by the computer which stores a plurality of application programs. Each of the application programs contains instructions which are executable by the computer to operate the printer. An application program can be selected by a user, or a host computer interfaced to the printer, or automatically by the printer, for execution by the computer. Utility files are also stored in the memory separate from the application programs which may include data and programs utilized by the selected application program. Such utility files include programs for barcode decoding, barcode encoding, and character rendering. The barcode decoding program utilizes Direct Memory Access (DMA) of the computer to capture values of a timer in the computer upon each transition in a scan data signal from the barcode scanner. The captured values are stored and then decoded to provide barcode data representing one or two-dimensional barcodes. The character rendering program provides for scaling of characters, defined in font files, to desired sizes. A graphical user interface may be used on the host computer interfaced to the printer to select various parameters of printer operation.

A portable printer is provided having a printer mechanism capable of printing on media and an RFID encoder for encoding information onto RFID circuits coupled to the media. The printer mechanism and RFID encoder are contained in the housing of the printer with a programmed controller for controlling the printer mechanism and RFID encoder. The printer mechanism includes a print head and motor for driving a platen roller to advance the media across the print head and passed the antenna of the RFID encoder. The media may be stored in a compartment in the housing on a roll or fan-fold in which multiple RFID circuits are provided along the length of the media. The programmed controller in the housing operates, responsive to communication received from a host terminal or computer, to send information to the print head to print information on the media and/or information to the encoder to encode the RFID circuit.

Portable printer with RFID encoder

A system is provided for RF communication between a host terminal or computer system (&ldquo;host&rdquo;) and a portable printer through RF signal transmissions. The host has a RF communication interface and is programmed to send and receive data via the interface to a portable printer. The portable printer has a printing mechanism for printing on media and a RF communication interface to send and receive data from a host. The printer is programmed to link with a host and then operate responsive to data received in RF signals from a host linked to the printer. Each portable printer has a unique serial number which is recorded in a barcode present on the housing of the printer and/or in an RFID tag coupled to the printer. The host has either, or both, an optical scanner or an RFID transmitter/receiver to read the printer's barcode or RF signals from the tag to obtain the printer's serial number. The host uses the serial number to identify a unique address associated with the printer by association between printer serial numbers and addresses. The host and printer are linked for RF communication by the host sending a first packet addressed to the printer utilizing the printer's address, the printer sending a second packet in response to the host, and the host sending a third packet directing the printer that it is linked to the host by the host's unique address for subsequent data communication there between, such that the printer responds to packets of data (commands and data) received from the host having the host's address. Other hosts can be similarly linked to the printer, such that when each of the hosts are linked to the printer, the printer is responsive to the linked host. Before the printer or the host sends a packet in a RF transmission, the printer or host may first find a clear channel for such transmission. The system may be used with multiple hosts and portable printers, such that different hosts can be linked to different printers.

A miniature printer is provided with a printer mechanism in a housing. A thermal printhead is fixedly mounted in the mechanism. The mechanism and the housing define a compartment for a roll of paper which is loosely disposed in the housing and is extended over the thermal printhead. The compartment is closed by a cover hinged to the housing at one end thereof. A platen roller is located in the cover in an opening larger than the shaft of the roller, which opening and cover provides a floating mount for the platen roller. A driven gear which rotates the platen roller is mounted on the shaft near one end thereof. A pair of hairpin springs have ends which are located in the path which the platen roller takes as the cover is closed and moves into engagement with the platen roller. The springs align the platen roller with the printing elements on the printhead and bias the platen roller into engagement with the printhead, while latching the platen roller and the cover in closed position. The driven gear on the shaft also is aligned with the last gear of a train of gears from a motor to drive the platen. The housing mounts the electronics of the printer, which are on a printed circuit board, and also a magnetic or smart card reader and encoder or separate magnetic card and smart card readers and encoders. The housing has another cover which extends from the cover carrying the platen roller and covers the housing while exposing an opening in the magnetic card reader and encoder across which a magnetic card may be swiped for reading the data or recording (encoding) new data on the magnetic track of the card. The other cover may have a separate receptacle for a smart card and an associated reader and encoder. The encoded card may be used as a smart card to enter places or operate devices, say in a hotel, casino or retail store.
