no. 1 Embodiment approach

[0053] Next, a first embodiment of the present invention will be described with reference to the drawings. Here, a laser printer is mentioned as an example of a printing device, but the gist of the present invention is not limited thereto, and obviously, it is also effective for a printing device using an LED dot matrix, a liquid crystal shutter (Shutter), etc. as a light emitting element. In addition, as the printing mechanism, a printing device using electrophotographic processing is taken as an example. However, it goes without saying that the gist of the present invention is that no matter what kind of printing mechanism the printing mechanism is, as long as it is manually fed for each page No matter what kind of printing mechanism (inkjet, serial, thermal transfer, etc.) is effective.

no. 2 Embodiment approach

[0141] Heretofore, an example in which each page constituting a document is printed page by page on the recording paper supplied from the manual paper feed port 305 has been described, but in this embodiment, an example in which a process is performed in which a series of documents are printed will be described. When a document (a file stored in the spool file 702) is set at the page arbitrarily set by the operator, the operation of the printing device is temporarily stopped, and the paper feeding from the paper feeding cassette 304 is switched to feeding from the manual paper feeding port 305. . Since the configurations of the host computer 101 and the printer in this embodiment are the same as those in the first embodiment, detailed descriptions are omitted here, and the content of this embodiment will be described with reference to the drawings described in the first embodiment.

no. 3 Embodiment approach

[0164] In the above-mentioned first embodiment and the above-mentioned second embodiment, the following case has been described, that is, the host computer 101 side recognizes that the user Figure 9 The paper feed key of the key is used to instruct to allow data transmission, and the compressed image data of a certain page is transmitted to the printing apparatus 100 .

[0165] However, the object of the present invention is not limited to this structure. For example, when the printing apparatus 100 has a memory with sufficient capacity to some extent, it may be assumed that all pages or a part of the pages of the compressed image data are sent from the host computer 101 in advance. At this time, the host 101 first responds to the user's Figure 9 The instruction of the paper feed key of the printer 100 recognizes the information indicating that the transmission of the print data notified from the printing apparatus 100 is permitted. Then, in response to the recognition, th...

Abstract

The invention provides an information processing apparatus, an information processing method, and a host-based printer. An information processing apparatus which controls a host-based printer includes a determination portion which determines designation of feed from a feed unit or manual feed port, a display control portion which, when it is determined that feed from the manual feed port is designated, causes a display portion to display a display to prompt the operator to insert a print medium into the manual feed port, an identification portion which identifies compressed-image data transfer permission corresponding a user instruction, and a transfer portion which transfers compressed image data of one page to the host-based printer.

Description

technical field [0001] The present invention relates to an information processing device, an information processing method, and a host-based printer. technical background [0002] In recent years, there has been an increase in demand for inexpensive and small-sized printing devices, and further cost reduction has been demanded. [0003] In order to prevent the recording paper loaded in the paper feed cassette from being erroneously fed instead of the recording paper originally fed from the manual paper feed port, there is an example of the configuration of the printing device and the host computer as follows: The off-line job command is embedded in the data sent from the host computer, and the CPU on the printer side interprets the command, and stops the operation of the printing device based on the command to avoid a gap between feeding of recording paper to the manual paper feeding port and printing. Execution timing is skewed. (For example, Japanese Patent Application L...
