It is determined on the host PC side whether or not two-way communication by radio communication is possible, and if two-way communication is possible, information indicating that two-way communication is possible is transmitted to the printer. On the printer side, identification information of the host PC which transmitted the information indicating that two-way communication is possible is registered.
Description
Technical field
The present invention relates to a kind of print system and Method of printing that is used for sending print data by radio communication.
Background technology
Traditionally, in the print system that comprises principal computer (main PC) and printer, main PC and printer interconnect by cable, the status information of representing various printer modes, comprise error message, residue China ink amount, battery capacity etc., (for example, prior art 1: TOHKEMY 2004-050726 communique) to be notified to main PC.
In this print system, main PC obtains order with status information and sends to printer, and the type of required status information is registered in the printer in advance.When the state information change of registered type, it is upgraded, and be read by poll (polling) by the status information of the type of main PC registration.In addition, propose a kind of like this print system in recent years again, in this print system, all status information can at random be sent to main PC from printer side, obtains order and need not send state information.
Now, as a kind of wireless data communication system, use with of bluetooth (Bluetooth) communication of 2.4GHz frequency band as spread-spectrum (spread spectrum) communication.
In Bluetooth communication, determine protocol subset (profile) according to each operating position, and communicate control according to each protocol subset.As the duplicating firmly in the cable reset protocol subclass (Hardcopy Cable Replacement Profile, hereinafter be called for short " HCRP ") of one of protocol subset, specified in more detail with main PC and printer or scanner between the relevant method of communication.In the HCRP protocol subset, communication is that logical link control and adaptation protocol (Logical Link Control andAdaptation Protocol is called for short " L2CAP " hereinafter) layer by Bluetooth communication carries out.48 unique bluetooth device address (being called for short " BD_ADDR " hereinafter) are assigned to Bluetooth communication device, and when connecting, notice BD_ADDR connects to be used for link.
In the HCRP protocol subset, provide two channels at the L2CAP layer.Main PC sends communication data on data channel, carry out various controls on control channel.In this print system, for example, according to the data flow con-trol on the data channel, its device (printer) receivable data word joint number on control channel is provided for the opposite end device (main PC) of this communication as credit (credit).The opposite end device of this communication sends communication data by data channel in this given credit scope.In addition, on control channel, can receive the device ID of printer.
Next explanation obtains the method for the status information between main PC and the printer.It should be noted that when printer and main PC interconnected by HCRP, in order to show the current state of printer in main PC side, status information can send from printer by data channel.Yet existence can not normally receive the device of printer modes information according to the regulation of protocol stack software.
The printed driver that is installed in main PC side judges whether to receive printer modes information by used protocol stack.If printed driver is judged this printer modes information and can be received, then this printed driver sends to printer so that required status information is registered to printer side by data channel with the status information order.On the other hand, printer side is checked its current state according to the status information order that receives, and sends the state that comprise error message, residue China ink amount, battery capacity etc. with predetermined form based on the status information of being registered on data channel.For printer modes is notified to the user, main PC side group is presented at information in the status information that receives on monitor of following this main PC etc.
In addition, when printed driver used among this main PC used protocol stack to judge this printer modes information can not to be received, this printed driver did not send the status information order that is used to receive printer modes information.
It should be noted, using Bluetooth communication to carry out under the situation of data communication, in order to prevent taking of wireless communication frequency band, perhaps in order to prevent current drain, perhaps owing to connect the regulation problem of restriction simultaneously, be that maximum seven devices are connected to a main equipment (master), send by data and carry out link connection and disconnection.In the HCRP print system, be that link connection and disconnection are carried out in a print job.Owing to status information obtains to order is a kind of print job, so all carrying out the link connection and disconnect when main PC send state information obtains to order at every turn, unless the link connection is established during printing waits.
As mentioned above because according to the main PC that connects the opposite end, some device can not carry out two-way communication, therefore, when status information accidentally when printer side sends to this device that can not two-way communication, on the opposite end device of communication, may go wrong.
Send state information order and carry out two-way communication when main PC that therefore, can two-way communication connects at each link.In order to check printer modes all the time and to discharge the printer that will use by other device, be necessary to prepare a kind ofly to be used for setting up that link connects, the processing of send state information order and receiving status information data during link connects in predetermined period.
In addition, when using Bluetooth communication, because link connects and disconnection is undertaken by each print job, printer is removed the Status Type of being registered when connecting.Therefore, when being connected with printer, main PC send state information obtains order to obtain printer modes information at every turn.For example, even do not print when handling when main PC monitor printer state, main PC also send state information obtains order.
In enabling the printer that order and interface seizure condition change according to the data communication that comes autonomous PC, when each the connection, all come under the situation of data communication of autonomous PC, interface seizure condition quilt is Iterim Change troublesomely.
In addition, under the situation of recent wired connection print system, obtain order without status information and can send whole status informations arbitrarily from printer side to main PC, this can be applied to Bluetooth communication.In the case, need in main PC, move the driver of normal receiving status information all the time.Yet printer always is not connected to so main PC.When application software that can not receiving status information or driver operated among the main PC, main PC sent the inexplicable data of printer, in main PC problem may take place.
