Printing system and program

1. A computer-readable medium storing thereon a program, the program causing a computer to control an operation of a printing apparatus, which includes an ink tank which is able to be supplemented with ink from the outside and an ejection head which ejects the ink supplied from the ink tank and which has a function of stopping ejecting the ink from the ejection head when a count value of an amount of ink supplied from the ink tank reaches a value limit, the program causing the computer to realize:

a first function of acquiring, from the printing apparatus, information used to determine whether the count value reaches the value limit;

a second function of displaying a confirmation image to prompt an operator of the printing apparatus to visually confirm an amount of ink in the ink tank, when the count value reaches the value limit; and

a third function of instructing the printing apparatus to perform a correction operation of returning the count value from the value limit by a predetermined value depending on selection of the operator of the printing apparatus after the display of the confirmation image.

2. The computer-readable medium according to claim 1 ,

wherein the second function displays an image to prompt the operator to determine whether it is necessary to supplement the ink, and

wherein the third function allows the printing apparatus to perform an initial operation to initialize the count value when the operator selects the supplement of the ink.

3. The computer-readable medium according to claim 1 ,

wherein the ink tank is configured such that a position of a ink level is visually viewed in the ink tank and has a lower limit line, which is used to determine whether it is necessary to supplement the ink in comparison to the position of the ink level,

wherein the second function displays, as the confirmation image, an image to prompt the operator of the printing apparatus to determine whether it is necessary to supplement the ink by comparing the lower limit line to the position of the ink level in the ink tank, and

wherein the third function allows the printing apparatus to perform the initial operation when the operator selects the supplement of the ink, whereas allowing the printing apparatus to perform the correction operation when the operator selects non-supplement of the ink.

4. The computer-readable medium according to claim 3 ,

wherein the ink tank stores a predetermined amount of ink below the lower limit line as reserved ink, and

wherein the third function allows the printing apparatus to perform, as the correction operation, an operation of returning the count value in the printing apparatus from the value limit by a count value corresponding to the amount of reserved ink.

5. The computer-readable medium according to claim 1 ,

wherein the printing apparatus includes a plurality of the ink tanks, each of which includes the ejection head, and has a function of stopping ejecting the ink for each of the ink tanks when the amount of ink counted for each ink tank reaches the value limit,

wherein the first function is a function of acquiring information used to determine whether the count value of the amount of ink reaches the value limit for each ink tank,

wherein the second function is a function of displaying the confirmation image for the ink tank in which the count value reaches the value limit, and

wherein the third function is a function of allowing one of the initialization operation to initialize the count value and the correction operation on each ink tank depending on selection of the operator of the printing apparatus for the ink tank displayed with the confirmation image.

6. A printing system comprising:

a printing unit having ejection head to eject ink supplemented from the outside to an ink tank; and

a control unit controlling an operation of the printing unit,

wherein the control unit includes

an ink amount count unit counting an amount of ink supplied from the ink tank to the ejection head in the printing unit as a count value,

an ejection stop unit stopping ejecting the ink from the ejection head, when the count value reaches a predetermined value limit,

a confirmation image display unit displaying a confirmation image to prompt an operator of the printing system to visually confirm the amount of ink in the ink tank, when the count value reaches the value limit, and

a count value change unit performing an operation of returning the count value to an initial value of the count value or returning the count value from the value limit by a predetermined value depending on selection of the operator of the printing system after the display of the confirmation image.

7. A computer-readable medium storing thereon a program, the program causing a computer to control an operation of a printing apparatus, which includes an ink tank which is able to be supplemented with ink from the outside and an ejection head which ejects the ink supplied from the ink tank and which has a function of stopping ejecting the ink from the ejection head when a count value of an amount of ink supplied from the ink tank reaches a value limit, wherein the ink tank is configured such that a position of an ink level is visually viewed in the ink tank and has a lower limit line, the program causing the computer to realize:

a first function of acquiring, from the printing apparatus, information used to determine whether the count value reaches the value limit;

a second function of displaying a message to confirm whether an ink level reaches the lower limit line or not and of displaying a check box,

a third function of determining whether the check box is checked or not and instructing the printing apparatus to perform the correction operation of returning the count value from the value limit by a predetermined value if the check box is checked.

8. The computer-readable medium according to claim 7 ,

the program further causing the computer to realize

a fourth function of displaying an image to prompt the operator of the printing apparatus to determine whether it is necessary to supplement the ink tank with the ink, and

a fifth function of instructing the printing apparatus to perform the initial operation to initialize the count value when the operator selects the supplement of the ink.
