Problems solved by technology
[0022] However, as described in the above Patent Document 1, in a configuration in which a plurality of computers connected to a network share one or more printers using a dedicated print server, configuration of client computer access status information is simple
However, a dedicated print server is costly and reduces the flexibility of this configuration
[0023] Furthermore, as described in Patent Document 2 above, in a configuration in which one of a plurality of computers is used as a server and the remaining computers are used as clients, when the client accesses state information stored in the common area of the server, The configuration becomes complicated
In addition to this, there is a problem that this configuration cannot handle the case where the operating system (hereinafter referred to as OS) of the client refuses bidirectional communication
[0024] According to the facts confirmed by the inventors, in a configuration where a computer installed with an operating system currently operating is used as a client, and a computer installed with the same or another operating system is used as a server, even if the client tries to obtain a connection to the server The status information of the printer, but because the two-way communication is rejected, the client cannot obtain the status information of the printer
[0025] The inventions described in Patent Documents 3 and 4 do not propose a solution to the problem that the configuration cannot handle the case where the client's OS refuses two-way communication

Embodiment Construction
[0041] A description is given of embodiments of the present invention with reference to the accompanying drawings. figure 1 It is a figure which shows the Example of this invention.
[0042] The system includes a server computer 1 (hereinafter referred to as server PC 1), a plurality of client computers 2 (hereinafter referred to as client PC 2), a network 3 connecting server PC 1 and client PC 2, and a network 3 connected to the server PC 1. Printer 4 for PC 1. The server PC 1 and the client PC 2 share the printer 4 through the sharing function of the OS.
[0043] Next, refer to figure 2 , giving a description of the printer drivers associated with the server PC 1 and the client PC 2.
[0044] First, the printer 4 includes: a host interface 41, which exchanges data and status information with a host computer (ie, the server PC 1); a host controller 42, which operates and controls a printer engine 43 based on print data received from the server PC Print out the print data...

A method for obtaining a status is disclosed in which a server computer and a client computer connected to a network share a printer connected to the server computer, and the client computer enables two-way communication and obtains status information of the printer via the server computer without depending on an operating system.
Description
technical field [0001] The present invention relates to a method for obtaining a status, a printer driver, and an information processing apparatus, and more particularly, to a method for obtaining a status, a printer driver, and information processing that are effectively applied to a case where a printer is shared by a plurality of computers equipment. Background technique [0002] Currently, as a system in which one or more printers are shared by a plurality of computers connected to a network, a configuration in which a dedicated print server is provided or a configuration in which a sharing system is embedded in an operating system of a computer is generally used. [0003] In the former print server configuration, computers connected to the network become clients. The client performs two-way communication with the print server in order to make reference to printer status information held in the print server. [0004] In such a configuration, for example, as described i...
