摘要:
Additive information for restoring the contour of image is generated and embedded in the image data. The format of the additive information is determined beforehand. When a hard copy is produced, the additive information is extracted from received image data. The additive information is for example very small characteristic points of a density different from the density assigned for image data and arranged inside the contour. The image data are restored according to the extracted additive information. The additive information can be generated for example from the code information for generating patterns such as control points data of outline font. For a half-tone image, a plurality of density bands are assigned to the additive information. A read error is detected by comparing the restored image with the received image data.

An image forming apparatus including a mechanism for forming a visual image on a sheet of paper and a plurality of sheets supply mechanisms each including a sheet storage cassette detachably incorporated therein. A detector for detecting the attaching operation of the sheet storage cassettes in each of the sheets supply mechanisms is also provided. An automatic selecting circuit, which is responsive to the detector, automatically selects the sheets supply mechanisms for which the attaching operation has been detected by the detector. A signal is generated to disable the automatic selecting circuit. The disabling signal enables operation without a cassette attached to the sheets supply mechanism irrespective of the sheet size selected.

A printer controller for controlling a printer shared with plural external data processors is disclosed.The printer controller includes a first memory for memorizing control data received from either one of the data processors when connected, a second memory for saving the received control data when another data processor is connected and a memory controller for saving the control data from the first memory to the second memory and for returning the control data from the second memory to the first memory when the printer is switched from one of the data processors to another one or vice versa.The printer controller further includes a communication device for controlling communication between either one of the data processors and the printer which is capable of identifying individual data processors.
摘要:
A printer apparatus which includes an image recording device for forming a visible image on a record medium, a memory unit for storing a plurality of different process programs each for controlling the operation of the image recording device, and a controller for controlling the image recording device in accordance with a selected one of the process programs for enabling the recording device to reproduce on the record medium an image corresponding to the image data supplied from a data processing device. The instruction signal from the data processing device is decoded and any one of the different process programs is selected on the basis of the decoded instruction signal, whereupon the image recording device is controlled in accordance with the selected process program for enabling the recording means to reproduce on the record medium an image corresponding to the image data supplied from the data processing device.
摘要:
A printer for printing bit images in accordance with printing information and control information which includes a detector for detecting when a print engine enters a predetermined state such as an abnormal state. A memory stores data relating to at least one page of bit images being printed at the time the predetermined state is entered. When the printing engine recovers from the predetermined state, the data stored in the memory are read out to immediately restart the printing operation.
摘要:
A control apparatus for controlling a printer in which a memory for memorizing data to be printed is sent from an external processor and a capability for deleting data memorized in the memory is provided. Data in memory is deleted according to a control code sent from the external data processor or entered through an operation panel. A range of data to be deleted is determined based on a control code given.
摘要:
In a printer apparatus wherein information relating to character patterns to be printed is received from an external source and is analyzed and converted into intermediate coded data, which are stored into a temporary memory and are thereafter successively read from the temporary memory to produce bit-map image data representative of the character patterns to be printed for each page of printed output, whereupon the bit-map image data is stored into a bit-map memory by referring to a font memory and the character patterns are printed on the basis of the bit-map image data read from the bit-map memory for each page of printed output, a method of conveniently converting the information received from the external source into the intermediate coded data, storing the intermediate coded data into the temporary memory and thereafter storing bit-map image data into the bit-map memory in accordance with the intermediate coded data read from the temporary memory. The information received from the external source is converted into the intermediate coded data preferably such that the intermediate coded data is particularly useful for having the character patterns printed in any desired orientations or attitudes on a print sheet.

There is disclosed a control apparatus for copying machines or the like which have a function of autoresetting operating conditions for the machine to standard conditions upon lapse of a specified period time after the completion of operation of the machine or after a predetermined input procedure and is operable with a key device associated with the machine for permitting the operation of the machine, wherein the control apparatus effects the autoresetting function to immediately reset the operating conditions to the standard conditions when the machine has been brought out of the operation permitted state by the key device, irrespective of lapse of the specified period of time for the autoresetting. When the user withdraws the key device from the machine, the operating conditions change to the standard conditions, thereby efficiently preventing the objection that the machine will subsequently operate under the conditions undesired by the next user.
