    • An apparatus (100) and method (200) that determines beam delays in a printing device is disclosed. The apparatus can include a photosensitive surface (110) and a raster output scanner (120) optically coupled to the photosensitive surface. The raster output scanner can include a first optical emitter (121) configured to scan a first beam across the photosensitive surface and at least one second optical emitter (122) configured to scan a second beam across the photosensitive surface to form an image on the photosensitive surface. The apparatus can include an integrated scan detector (130) configured to detect the beams from the raster output scanner and configured to produce a signal based on the beams detected from the raster output scanner. The apparatus can include a beam calibration controller (140) coupled to the integrated scan detector. The beam calibration controller can be configured to determine at least one beam delay between the first optical emitter and the at least one second optical emitter based on signals from the integrated scan detector. The beam calibration controller can be configured to delay operation between the first optical emitter and the at least one second optical emitter based on the at least one beam delay.

    • A scanner communicates with a microcomputer over a serial communications link utilizing the serial I/O port of the microcomputer. Both signals representing the data which is scanned and signals representing commands to the scanner and commands from the scanner indicative of the status thereof (e.g., scanner trigger actuation) are communicated over a plurality of lines in the communication link. These lines may be of the type utilized for transmission of data and commands in accordance with a communications protocol, such as the RS-232 protocol. Interrupts are generated when the scanner is connected to the serial port via the communication link and the microcomputer is available for decoding. Then appropriate interrupts are generated to actuate the scanner and to respond to the data. The scanner may be a laser or optical beam scanner or a wand which is moved across a bar code symbol. The symbol has bars which are relatively opaque and reflective (black or white). The microcomputer translates the data which represents the width of each bar and the number of bars and the detection of the end of a bar code symbol (Quiet Zone) into digital values which are stored in memory and presented for decoding in accordance with programming of the microcomputer which decodes the symbol. The decoded symbol may be displayed graphically, with its opaque and reflective bars and the alphanumerics which the symbol represents, on the screen of a terminal including the microcomputer.
    • 扫描仪通过使用微型计算机的串行I / O端口的串行通信链路与微型计算机进行通信。 表示被扫描的数据的两个信号和表示扫描仪的命令的信号和来自扫描器的指示其状态的命令(例如,扫描仪触发器致动)在通信链路中的多条线路上传送。 这些线路可以是用于根据诸如RS-232协议的通信协议传输数据和命令的类型。 当扫描器通过通信链路连接到串行端口并且微型计算机可用于解码时,产生中断。 然后产生适当的中断来启动扫描仪并响应数据。 扫描器可以是激光或光束扫描器或者通过条形码符号移动的魔杖。 该符号具有相对不透明和反射(黑色或白色)的条形。 微型计算机将代表每个条的宽度和条数的数据和条形码符号(静音区)的结尾的检测数据转换成存储在存储器中的数字值,并根据 对符号进行解码的微机。 在包括微型计算机的终端的屏幕上,解码符号可以以其不透明和反射条以及符号表示的字母数字图形显示。
