Printer driver program installed on both terminal and server

1. A non-transitory computer-readable recording medium storing a controlling program for a terminal, wherein the controlling program is a printer driver program for the terminal that communicates with a server and an image forming apparatus, and wherein the controlling program causes a computer to:

acquire a first time stamp from the server,

determine whether the first time stamp and a second time stamp stored in the ten final are identical,

acquire information of the image forming apparatus when the first time stamp and the second time stamp are different, and

update content of the second time stamp to content of the first time stamp when the first time stamp and the second time stamp are different.

2. The non-transitory computer-readable recording medium storing the controlling program for the terminal according to claim 1 , wherein the controlling program further causes the computer to:

not acquire the information of the image forming apparatus from the image forming apparatus when the first time stamp and the second time stamp are same.

3. The non-transitory computer-readable recording medium storing the controlling program for the terminal according to claim 1 , wherein the controlling program further causes the computer to:

acquire the information of the image forming apparatus from the image forming apparatus when the terminal does not store the second time stamp.

4. The non-transitory computer-readable recording medium storing the controlling program for the terminal according to claim 1 , wherein the controlling program further causes the computer to:

store the acquired information of the image forming apparatus, and

display, on the terminal, a setting screen for printing to be executed by the image forming apparatus, wherein the setting screen reflects the stored information of the image forming apparatus.

5. A non-transitory computer-readable recording medium storing a controlling program for a server, wherein the controlling program is a printer driver program for the server that communicates with a terminal, wherein the controlling program causes a computer to:

receive an instruction to change setting values stored in a printer driver program being installed on the server,

change a setting value stored in the printer driver program in accordance with the received instruction, when the instruction was received,

update a time stamp stored in the printer driver to reflect a time and date when the setting value stored in the printer driver program is changed,

search for another printer driver program being installed on the server, in which a setting value is to be changed, when the instruction was received,

change the setting value stored in the another printer driver program, in accordance with the received instruction, and

update a time stamp stored in the another printer driver to reflect the time and date when the setting value stored in the another printer driver program is changed.

6. A non-transitory computer-readable recording medium storing a controlling program for a server and a terminal, wherein the server and the terminal configures an image forming system with an image forming apparatus, the controlling program is a printer driver program for the server, and the terminal communicates with the server and the image forming apparatus, wherein the controlling program causes a computer to:

receive an instruction to change setting values stored in printer driver programs being installed on the server, at the server,

change a setting value stored in the printer driver program in accordance with the received instruction when the instruction was received, at the server,

search for another printer driver program being installed on the server, in which a setting value is to be changed, when the instruction was received, at the server,

change the setting value stored in the another printer driver program, in accordance with the received instruction, at the server,

acquire a first time stamp from the server by the terminal when the setting value stored in the printer driver programs is a predetermined value,

determine whether the first time stamp and a second time stamp stored in the terminal are identical, by the terminal,

acquire information of the image forming apparatus by the terminal, when the first time stamp and the second time stamp are different, and

update content of the second time stamp to content of the first time stamp by the terminal, when the first time stamp and the second time stamp are different.

7. A terminal comprising a processor that:

acquires a first time stamp from the server,

determines whether the first time stamp and a second time stamp stored in the terminal are identical,

acquires information of the image forming apparatus, when the first time stamp and the second time stamp are different, and

updates content of the second time stamp to content of the first time stamp, when the first time stamp and the second time stamp are different.

8. The terminal according to claim 7 , wherein

the processor does not acquire the information of the image forming apparatus from the image forming apparatus, when the first time stamp and the second time stamp are same.

9. The terminal according to claim 7 , wherein the processor further:

acquires the information of the image forming apparatus from the image forming apparatus, when the terminal does not store the second time stamp.

10. The terminal according to claim 7 , wherein the processor further:

stores the acquired information of the image forming apparatus, and

displays on the terminal, a setting screen for printing to be executed by the image forming apparatus, wherein the setting screen reflects the stored information of the image forming apparatus.

11. A server comprising a processor that:

receives an instruction to change setting values stored in a printer driver program being installed on the server,

changes a setting value stored in the printer driver program in accordance with the received instruction when the instruction was received,

updates a time stamp stored in the printer driver to reflect a time and date when the setting value stored in the printer driver program is changed,

searches for another printer driver program being installed on the server, in which a setting value is to be changed when the instruction was received,

changes the setting value stored in the another printer driver program, in accordance with the received instruction, and

updates a time stamp stored in the another printer driver to reflect the time and date when the setting value stored in the another printer driver program is changed.
