Abstract

PROBLEM TO BE SOLVED: To shorten the first page print time by storing an image data temporarily, calculating a time required for development based on the size of a recording medium and starting a recovery means such that recovery is finished before finishing development based on the time required for recovery. SOLUTION: When a recorder 101 makes a decision that reception of a command from a host 104 has ended, setting process is executed in case of a sheet size command. The time for starting recovery processing is then calculated and a timer for counting the calculated time is actuated. The timer is decrimented at a specified time interval and recovery processing is executed when the count reaches 0. In response to reception of the sheet size command, the time for starting recovery processing is calculated from the time required for developing a corresponding data. Since the recovery process is executed before starting a recording operation based on the calculated time, data developing process and recovery process can be executed in parallel.

When the above-mentioned command is transferred from the host, the recording apparatus executes command reception and data expansion processing in the following procedure.

FIG. 7 is a flowchart showing the command receiving and data expanding processing.

According to this flowchart, first, in step S700, the recording apparatus is in a state of waiting for data reception from the host, and upon detecting reception of a command, the processing proceeds to step S701. In step S701, it is determined whether or not the command reception has been completed. If the command is being received, the process returns to step S700 to continue the reception process. On the other hand, if it is determined that the command reception has been completed, the process proceeds to step S702.

Next, the process proceeds to step S702.
It is determined whether or not the received command is a “paper size command”. If the received command is the command, the process proceeds to step S703 to execute a paper size setting process. Thereafter, the process proceeds to step S704, in which a time for starting the recovery process is calculated, and in step S705, a timer for counting the calculated time is started. Here, the value initially set in the counter of the timer is determined in step S70.
4 is the time calculated. The interrupt processing by the timer will be described later.

For example, (1) the time required for the recovery processing (including the time for moving the recording head to the recording position) is 20 (seconds);
(2) If the area of the recording paper size is 5 × 10 4 (mm 2), as shown in FIG. 6, in the recording apparatus of this embodiment, the data development time is 50 (seconds).
The time (time) at which the recovery processing starts is 30 (seconds) = 50−20 after the start of the data development processing.

After starting the timer, the process proceeds to step S70
It returns to 0 and waits for the next command.

On the other hand, if the received command is not the "paper size command", the process proceeds to step S706, where it is determined whether the received command is the "record number command". If so, the process proceeds to step S707.
To execute the required number-of-records setting process. Thereafter, the process returns to step S700, and waits for reception of the next command.

On the other hand, if the received command is not the "record number command", the process advances to step S708 to check whether the received command is a "raster skip command". If so, the process goes to step S7.
In step 09, the Y coordinate value is updated. afterwards,
The process returns to step S700 to wait for the next command.

On the other hand, if the received command is not the "raster skip command", the process proceeds to step S71.
In step S711, it is checked whether the received command is a “CR command”.
And the X coordinate value is updated. Thereafter, the process returns to step S700, and waits for reception of the next command.

On the other hand, if the received command is not the “CR command”, the process proceeds to step S712,
It is checked whether or not the received command is a “raster image command”.
Then, the bit image data set in the "raster image command" is developed in the print buffer 704. Thereafter, the process returns to step S700, and waits for reception of the next command.

On the other hand, if the received command is not the "raster image command", the process proceeds to step S71.
In step S7, it is determined whether the received command is a "recording start command".
Proceed to step 15 to start the recording process. Thereafter, the process returns to step S700, and waits for reception of the next command.

On the other hand, if the received command is not the “recording start command”, the process proceeds to step S716, in which the received command is regarded as a command that cannot be handled by this recording apparatus, and is ignored. The process returns to step S700 to wait for the next command.

FIG. 8 is a flowchart showing the interrupt processing of the timer started in step S705.

First, in step S800, the value of the timer counter is decremented by "-1" at predetermined time intervals (for example, one second). Next, in step S801, it is checked whether the value of the counter has become "0". Here, if it is confirmed that the value has become “0”, the process proceeds to step S802, and executes a recovery process.

On the other hand, if the value of the counter has not yet become "0", the process returns to step S800, and the monitoring by the timer is continued.

As described above, in this embodiment, the recovery process is started and executed before automatically starting the recording operation based on the value calculated in step S704.

FIG. 9 is a comparison table of the first page print time in the recording apparatus of this embodiment and the first page print time according to the prior art.

As is apparent from this figure, the first page print time is significantly reduced.

Therefore, according to the above-described embodiment, when the command for setting the paper size is received, the time at which the recovery process is started is calculated from the time required for developing the image data corresponding to the paper size. Since the recovery processing is performed before the recording operation is started based on the calculated time, the data development processing and the recovery processing can be executed in parallel, and the first page print time can be greatly reduced.

In this embodiment, an example has been described in which the time required for moving the recording head to the recording position is included in the recovery processing. However, the present invention is not limited to this. The apparatus may be configured to execute at the recording position, and may not be included in the time required for the recovery processing.

Further, in addition to the configuration described in this embodiment, the elapsed time from the time when the previous recording operation was executed is measured, and the recovery processing method and time to be executed before the recording operation are selected according to the elapsed time. It is also possible to calculate the time to start the recovery process before the recording operation according to the recovery time.

[0055]

[Other Embodiments] In the printing apparatus used in the above-described embodiment, after receiving bit image data of a predetermined raster (for example, 100 rasters) from the start of reception of raster image data to the start of printing, a recovery process is performed. May be automatically started.

FIG. 10 is a flowchart showing a command receiving and data expanding process according to this embodiment. In FIG. 10, the same processing steps as those already described in the above-described embodiment are denoted by the same reference numerals, and description thereof will be omitted.

According to the flowchart shown in FIG. 10, after the paper size is set by the processing of steps S700 to S703, the processing proceeds to step S720 to calculate the total number of rasters of the image to be drawn on the set recording paper. I do. Thereafter, the process returns to step S700, and waits for reception of the next command.

If it is determined in step S712 that the received command is a "raster image command", the process advances to step S721 to execute a raster image receiving process. Thereafter, the process returns to step S700, and waits for reception of the next command.

The raster image receiving process will be described with reference to the flowchart shown in FIG. The process shown in FIG. 11 is a process for each raster reception.

First, in step S1016, it is checked whether or not the received raster image is the first raster. If the reception is the first raster, the process advances to step S1017 to start a timer and start measuring the reception time of the raster image. After that, the process advances to step S1022 to execute a process of expanding the received data.

On the other hand, if the reception is not the first raster, the process proceeds to step S1018 to check whether the reception is the 100th raster. If the received data is not the 100th raster, the process proceeds to step S1022, and the received data is expanded. On the other hand, if the reception is the 100th raster, the process proceeds to step S1019.

In step S1019, the time from the reception of the first raster to the reception of the 100th raster is determined in step S1.
It reads from the timer which started measurement in 017. Next, in step S1020, based on the total number of rasters calculated in step S720 and the timer value read out in step S1019, a standby time until a recovery process is started after a bit image of 100 rasters is received is determined. Calculation is performed, and the calculated value is set again as the initial value of the timer counter.

For example, when recovery processing is started after receiving bit image data for 100 rasters,
(1) The time required for receiving the bit image data for 100 rasters is 1 second, and (2) Step S
It is calculated from the processing in 720 that the total number of received rasters is 3000 rasters. (3) Assuming that the time required for recovery (including the time for moving the recording head to the recording position) is 20 (seconds), 100 rasters are calculated. The time required from completion of reception until completion of reception of all remaining raster data is (300
0-100) ÷ 100 × 1 = 29 (seconds).
Therefore, 29-20 = 9 seconds is set in the counter of the timer.

Then, in step S1021, a timer is started based on the set initial value. After the activation, time monitoring is performed as shown in FIG. 8, and when the value of the counter becomes "0", a recovery process is executed.

Therefore, according to this embodiment, the time from the start of the raster image reception to the reception of a predetermined amount of data is measured, and the time is measured based on the total reception raster number calculated from the measured time and the set recording paper size. Thus, the recovery processing can be automatically started during the reception of the raster image so that the time at which the recovery processing is started can be obtained, and the recovery processing can be completed at the same time that the reception of the raster image is completed.

The above-described embodiment is suitable for recording a color image on a label. However, after the recording data is expanded in a print buffer in units of one page, recording is performed based on the contents of the print buffer. The present invention is not limited to the type of recording device as long as the recording device performs the recording.

The above-described embodiment is particularly provided with a means (for example, an electrothermal converter or a laser beam) for generating thermal energy as energy used for performing ink ejection even in an ink jet recording system. By using a method in which a change in the state of the ink is caused by energy, it is possible to achieve higher density and higher definition of recording.

The typical structure and principle are described in, for example, US Pat. Nos. 4,723,129 and 4,740.
It is preferable to use the basic principle disclosed in the specification of Japanese Patent No. 796. This method can be applied to both the so-called on-demand type and continuous type. In particular, in the case of the on-demand type, liquid (ink)
By applying at least one drive signal corresponding to the recorded information and providing a rapid temperature rise exceeding the film boiling to the electrothermal transducer arranged corresponding to the sheet or the liquid path holding the Since thermal energy is generated in the electrothermal transducer and film boiling occurs on the heat-acting surface of the recording head, bubbles in the liquid (ink) corresponding to this drive signal on a one-to-one basis can be formed. It is valid. By discharging the liquid (ink) through the discharge opening by the growth and contraction of the bubble, at least one droplet is formed. When the drive signal is formed into a pulse shape, the growth and shrinkage of the bubble are performed immediately and appropriately, so that the ejection of the liquid (ink) having particularly excellent responsiveness can be achieved, which is more preferable.

As the pulse-shaped drive signal, those described in US Pat. Nos. 4,463,359 and 4,345,262 are suitable. Further, if the conditions described in US Pat. No. 4,313,124 relating to the temperature rise rate of the heat acting surface are adopted, more excellent recording can be performed.

As the configuration of the recording head, in addition to the combination of a discharge port, a liquid path, and an electrothermal converter (a linear liquid flow path or a right-angle liquid flow path) as disclosed in the above-mentioned respective specifications, A configuration using U.S. Pat. No. 4,558,333 or U.S. Pat. No. 4,459,600, which discloses a configuration in which a heat acting surface is arranged in a bent region, is also included in the present invention. In addition, for multiple electrothermal transducers,
JP-A-59-123670 which discloses a configuration in which a common slot is used as a discharge part of an electrothermal transducer, and JP-A-59-123670 which discloses a configuration in which an opening for absorbing a pressure wave of thermal energy corresponds to a discharge part. A configuration based on 138461 may be adopted.

Further, as a full line type recording head having a length corresponding to the width of the maximum recording medium that can be recorded by the recording apparatus, the length is determined by a combination of a plurality of recording heads as disclosed in the above specification. This may be either a configuration satisfying the above requirements or a configuration as a single recording head formed integrally.

In addition to the cartridge type recording head in which the ink tank is provided integrally with the recording head itself described in the above embodiment, the recording head is electrically connected to the apparatus main body by being mounted on the apparatus main body. A replaceable chip-type recording head, which enables a simple connection and supply of ink from the apparatus main body, may be used.

It is preferable to add recovery means for the printhead, preliminary auxiliary means, and the like to the configuration of the printing apparatus described above, since the printing operation can be further stabilized. Specific examples thereof include capping means for the recording head, cleaning means, pressurizing or suction means, preheating means using an electrothermal transducer or another heating element or a combination thereof. It is also effective to provide a preliminary ejection mode for performing ejection that is different from printing, in order to perform stable printing.

Further, the recording mode of the recording apparatus is not limited to the recording mode of only the mainstream color such as black, but may be a single recording head or a combination of plural recording heads. Alternatively, the apparatus may be provided with at least one of full colors by color mixture.

In the embodiments described above, the description is made on the assumption that the ink is a liquid. However, even if the ink solidifies at room temperature or lower, it is possible to use an ink that softens or liquefies at room temperature. Or, in the ink jet method, generally, the temperature of the ink itself is controlled within a range of 30 ° C. or more and 70 ° C. or less to control the temperature so that the viscosity of the ink is in a stable ejection range.
It is sufficient that the ink is in a liquid state when the use recording signal is applied.

In addition, in order to positively prevent temperature rise due to thermal energy as energy for changing the state of the ink from a solid state to a liquid state, the temperature is positively prevented.
Alternatively, in order to prevent evaporation of the ink, an ink which solidifies in a standing state and liquefies by heating may be used. In any case, the application of heat energy causes the ink to be liquefied by the application of the heat energy recording signal and the liquid ink to be ejected, or by the time the ink reaches the recording medium, the solidification of the ink already begun. The present invention is also applicable to a case where an ink having a property of liquefying for the first time is used. In such a case, as described in JP-A-54-56847 or JP-A-60-71260, the ink is held in a liquid state or a solid state in the concave portion or through hole of the porous sheet. It is good also as a form which opposes an electrothermal transducer. In the present invention, the most effective one for each of the above-mentioned inks is to execute the above-mentioned film boiling method.

Further, as a form of the recording apparatus according to the present invention, an image output terminal of an information processing apparatus such as a computer may be integrally or separately provided as an image output terminal, or an image input apparatus such as a digital camera may be combined. The apparatus may take the form of an apparatus that collectively performs photographing and printing.

[0078]

As described above, according to the present invention, when recording on a recording medium using a recording head that discharges ink in accordance with an ink-jet method and when recovering the recording head are performed, the recording medium is recovered. A size is set, and based on the set size of the recording medium, a time required to develop image data necessary for recording on the recording medium of the size on the storage medium is calculated, and the input image data is stored in the storage medium. Although the image data is expanded based on the calculated time required for the expansion and the time required to execute the recovery operation, at least the recovery is started so that the recovery operation is completed before the expansion is completed. And the printhead recovery operation are performed in parallel, so that the first page print time can be reduced even if the recovery operation is performed before the print operation. There is an effect that.

As a result, the time required for total recording is reduced, which contributes to achieving high-speed recording.
