Printer 10 is in order to send condition information to principal computer 86,3 kinds of situations of (1)~(3) below mainly containing.
(1) normal condition information sends
So-called normal condition information sends, and is meant that replying the situation of being sent here from principal computer 86 requires instruction and send condition information.Situation requires instruction, is a kind of to the steering order of printer 10.CPU84 as principle, is the steering order that printer 10 is accepted according to the sequential processes of being accepted.Therefore, normal condition information sends, and is to utilize under the situation of the condition notification that does not have certain emergency to require.
(2) real time status information sends
So-called real time status information sends, and is meant for being required instruction and send replying of condition information by the situation of sending as real-time command from principal computer 86.At this moment, real-time command is the instruction of carrying out priority processing than other steering orders sent here from principal computer 86 or print data etc., and when printer 10 had been accepted real-time command, CPU84 more preferably handled real-time command earlier than other steering orders of accepting.Therefore, real time status information sends, and is to utilize under the situation of the condition notification that has emergency to require.
(3) condition information sends (ASB:Auto Status Back) automatically
So-called condition information automatically sends, and when being meant the changed condition of printer 10,10 pairs of principal computers 86 of printer automatically send condition information.Printer 10 when changing from the specified situation division state of the ASB setting command of principal computer 86 in advance, is directly divided state notifying principal computer 86 with the situation of its variation.Send with this automatic condition information, only send condition information to principal computer 86 where necessary, promptly finish less so send number of times, and promptly can finish, therefore also can reduce the load of transmission with minimal transmission.
But, as mentioned above, the printer 10 of present embodiment, therefore the structure that can not print when having the state of opening when rear portion cover 16, is provided with cover opening and closing sensor 42, the open mode of detection rear portion cover 16 (below, be also referred to as the apparatus lid opening state), and export its condition information.On the other hand, according to the kind of printer, the printer that can print being arranged also under the apparatus lid opening state, in such printer, do not have the measuring ability of cover opening and closing, therefore, also is the machine of not exporting the condition information of expression cover opening and closing state.Therefore, be installed on the application program in the principal computer 86, be to be prerequisite with the printer that do not have the measuring ability that detects the cover opening and closing function, when the condition information of not corresponding expression cover opening and closing state, in case this printer is replaced into printer 10, the problem of aforesaid this application program nonrecognition from the condition information of the expression cover opening and closing state of printer 10 outputs will take place.
For the such situation of correspondence, the printer 10 of present embodiment, when detecting the apparatus lid opening state, have with its state exchange for the expression no printer paper state (below, be called no paper state) condition information and the function (below, be called the situation translation function) of output.Concrete is, when detecting the apparatus lid opening state, CPU84 generates and has or not the situation of printer paper to divide the binary column that is set at " 1 " (no paper) expression, and this binary column is sent in the principal computer 86 as condition information.Like this, on principal computer 86, can be no paper state, and can take and countermeasure same when the no paper state the apparatus lid opening state confirmation of printer 10.
At this moment, when the apparatus lid opening state, the condition information that why sends no paper state be the reasons are as follows.That is, because which kind of printer no matter all is that non-print is moved under the state of no printer paper, so almost can both discern the situation of no paper state in all application programs.In addition, can stop to print when the apparatus lid opening state with the printer 10 of present embodiment, in this, general with the situation of the state of no paper.Therefore, when cover sends the condition information of no paper state during in open mode, so that take adequate measures in the application program side.
And, what is called is opened the situation of cover, can be thought of as the situation that changes the paper roll kind except carry out the paper roll replacing because of the paper roll that is not contained, in addition as recording medium, even but the latter's situation, be replaced with on the new paper roll this point at the paper roll that will be taken in, general with no paper state.
Printer 10, have expression situation translation function effectively/invalid set information (below, be called the conversion set information), according to this information, whether decision is replaced into the situation of apparatus lid opening state the situation of no paper state.The conversion set information is stored in the non-volatile memory 94 that printer 10 has.Be stored in method in the non-volatile memory 94 with changing set information like this, no matter the power supply of printer 10 is disconnected, or carries out that hardware is provided with again or software is provided with again, can store to keep its content.Therefore, in the time of can omitting at every turn the power connection with printer 10, revise the trouble of setting again and again.In addition, the conversion set information also can send by the instruction from principal computer 86 or import from the operation of printer panel, writes in the non-volatile memory 94.But, the mechanism that has kept the conversion set information as storage, except above-mentioned non-volatile memory 94, also can be with the storing mechanism of machineries such as switch of inclination.
Be set to when effective in case Fig. 6 is the situation translation function, then be illustrated in the value that each situation in each of invalid setting situation is divided.As shown in the drawing, be set to when effective in the situation translation function, under the apparatus lid opening state, expression has or not the situation of printer paper to divide to be set to " 1 " (no paper).On the other hand, be set to when invalid in the situation translation function, the situation division that to represent the cover opening and closing state under the apparatus lid opening state is set to " 1 " (apparatus lid opening), and expression has or not the situation of printer paper to divide, in fact only is set to " 0 " (paper is arranged) at no paper state, all is not set at " 1 " (no paper) so long as there is the paper state.
Fig. 7 is with the process flow diagram of condition information to the practiced program of CPU84 of principal computer 86 transmissions.This program can carried out above-mentioned (1) normal condition information transmission, and (2) real-time information sends, and (3) are any situation starting of condition information transmission automatically.As shown in the drawing, at first, according to each testing result generating state information (S101) of printer paper test section 102 or fault detect portion 104, cover test section 100 etc.Then, read conversion set information (S102),, judge situation translation function whether effectively (S103) according to this conversion set information from non-volatile memory 94.Consequently, if the situation translation function is effective, then then judge according to the testing result of cover test section 100 whether cover opens (S104).Consequently, when detecting the apparatus lid opening state, be set to " 1 " (no paper) (S105) corresponding to the scale-of-two that has or not printer paper in the condition information, this condition information is sent to principal computer 86.On the other hand, when the situation translation function is invalid in S103, and when not being the apparatus lid opening state in above-mentioned S104, the condition information in that S101 generates intactly is sent to principal computer 86 (S106).
In addition, in above-mentioned program, at first, and on the basis of generating state information according to each testing result, the situation translation function is effectively, and cover will be represented that the scale-of-two that has or not printer paper of the condition information that generated changes during for open mode and be decided to be " 1 " (no paper), but be not limited to this, in the stage of initial generating state information, the situation translation function is effectively, and, if the apparatus lid opening state then also can be made as " 1 " with the scale-of-two that has or not printer paper of expression condition information.
As described above, in the present embodiment, be set as when effective in the situation translation function, with the situation of apparatus lid opening state be replaced into no paper state condition information, be sent to principal computer 86.Therefore, being installed in the working procedure on the principal computer 86, when correspondence is represented the situation of the open and-shut mode of cover, with the conversion set information situation translation function being made as effectively, in application program, can be no paper state with this with the apparatus lid opening state confirmation.Then, with no paper state and apparatus lid opening state, take common countermeasure in the application program side.Therefore, according to present embodiment, even application program does not change this application program when the situation of not corresponding expression cover opening and closing state, only the situation translation function is made as effectively, just can carries out the correct processing of corresponding apparatus lid opening state with the conversion set information.That is, do not change the application program of the condition information of not corresponding expression cover opening and closing state, just the printer 10 that can corresponding have cover opening and closing status detection function.
In addition, in the above-described embodiments, printer 10 is printers of putting the formula of shaking, but the present invention no matter be the ink-jetting style or the printing type of heat-sensitive type, can be applicable to the printer with cover opening and closing status detection function all sidedly.
