A printing system includes a storage unit that associates and stores print job data and post processing job data; a printing unit that prints a code regarding the association on media when an image is printed on the media based on the print job data; a code reading unit that reads the code that is printed on the media; and a post processing unit that selects the post processing job data that is associated from the storage unit based on the read code and performs the post processing with respect to the media based on the selected post processing job data.

A printing head structure of calculator, including a belt type printing head the outer periphery of which is disposed with at least one group of fine characters and at least one group of coarse characters. The fine characters have the same symbols and numerals as the coarse ones, while having different thicknesses and letterforms. By means of a printing control program of the calculator, the printing head is able to print out a positive or negative result respectively by fine characters or coarse characters so as to apparently visually distinguish the positive result from the negative one and thus achieve a reliably reminding effect.

Mask size data M and a sharpness enhancement coefficient K are set in accordance with the pixel density of image data S.sub.ij * to be output. The image data S.sub.ij * is determined asS.sub.ij *=S.sub.ij +K.multidot.(S.sub.ij -U.sub.ij)using the mask size data M and the sharpness enhancement coefficient K, wherein the smoothed image data U.sub.ij is defined by the following equation: ##EQU1##
摘要:
A printer has a memory containing print information on a plurality of characters, grouped by a print pressure of the character, and a control unit for controlling the print pressure in accordance with the print information stored in the memory. The memory stores the print information for each print pressure group in ascending order. The duration of the impact pulse is determined once the character's code is found in the list of characters stored in order of lowest to highest impact energy, based on character size.
摘要:
A composite printing apparatus including a first printing assembly which has character fonts, and a second printing assembly for printing characters with a matrix of dots, wherein a series of input printing data corresponding to a plurality of successive characters are classified into a first group of printing data for a first printing with the character fonts of the first printing assembly, and a second group of printing data for a second printing with the matrix of dots of the second printing assembly. One of the first and second printing assemblies is first activated according to corresponding one of the first and second groups of printing data, and subsequently the other printing assembly is activated according to the other one of the first and second groups of printing data.

A phase lock loop oscillator is provided with a voltage controlled oscillator which includes a current controlled oscillator and an input controller therefor that maintains the center frequency of the current controlled oscillator substantially constant irrespective of changes in the gain of the voltage controlled oscillator.
摘要:
An electric printer which allows sure printing which depends on identity ween the orders given on the keyboard and the movement of the printing wheel. It includes means for uncoupling the drive shaft from the wheel and two sensors one of which indicates the position of the drive shaft and the other of which indicates the number of positions passed by the wheel before it stops. Application to a printer used for counting.

A serial printer comprises a carriage, a print member rotatably mounted to the carriage and including a plurality of character elements, a first drive coupled to the print member for rotating the print member to a desired rotational position in order to place a selected character element at a printing position adjacent a record medium to be printed upon, a second drive coupled to the carriage for moving the carriage along a predetermined path whereby the print member is caused to move to a desired printing position along the path, a first servo control coupled to the first drive and responsive to a first set of input data and instructions for controlling the direction and speed of rotation of the print member, a second servo control system coupled to the second drive and responsive to a second set of input data and instructions for controlling the direction and speed of movement of the carriage, and a programmed data processor coupled to the first and second servo control system for supplying at least some of the first set of input data and instructions under program control to the first servo control system and at least some of the second set of data and instructions to the second servo control system.
摘要:
A printing apparatus for an electronic calculator or the like comprises a first type wheel formed with mathematical operator symbols which is fixed to a spline shaft and a second type wheel formed with digits which is slidably mounted on the spline shaft for integral rotation. A stepping motor rotates the spline shaft for character selection. A carriage is connected to the second type wheel and is movable by a cable wound around drive and take-up spools to move the second type wheel along the spline shaft for serial feed. A single electrical solenoid actuates a printing hammer for printing and subsequently actuates a ratchet and pawl mechanism to serially feed the second type wheel by one character position in one reciprocation of the solenoid plunger. A linkage initially connects the plunger to a first printing hammer associated with the first type wheel to print the mathematical operator and subsequently to a second printing hammer associated with the second type wheel to serially print digits from least significant to most significant.
