Recording medium

1. A non-transitory computer-readable recording medium storing an installer program that is for execution by a computer in a terminal device to install a driver program on the terminal device when a user of the terminal device joins a target group to which an image forming apparatus of a specific model supported by the driver program is assigned, the installer program causing the computer to:

display an operation screen on a display device of the terminal device, the operation screen including a first operation element to be selected when the user joins the target group without having previously belonged to any other groups and a second operation element to be selected when the user joins the target group as a result of transfer from a former group to which the user formerly belonged;

in response to selection of the first operation element by the user,

control the image forming apparatus to create therein a document box for the user and

add membership information of the user to group management data managed by a predetermined server; and

in response to selection of the second operation element by the user,

control the image forming apparatus to create therein a document box for the user,

identify an image forming apparatus assigned to the former group with reference to the group management data,

control the identified image forming apparatus to delete a document box created therein for the user, and

add membership information of the user to the group management data, wherein

the membership information includes identification information of the user and identification information of the image forming apparatus assigned to the target group,

the group management data includes, for each of a plurality of users, history data including identification information of image forming apparatuses assigned to groups to which the corresponding user has belonged, the history data being based on membership information having been added to the group management information for the corresponding user,

the membership information includes document box creation information indicating whether or not a document box is successfully created for the user,

the group management data includes, for each of the plurality of users, document box information indicating whether or not image forming apparatuses assigned to groups to which the corresponding user has belonged have a document box created for the corresponding user, and

the installation program further causes the computer to:

update the document box information based on the membership information;

determine, based on the document box information, whether or not the identified image forming apparatus has a document box created for the user;

on determining that the identified image forming apparatus has a document box created for the user, transmit an instruction to delete the document box to the identified image forming apparatus; and

on determining that the identified image forming apparatus does not have a document box created for the user, not transmit an instruction to delete the document box to the identified image forming apparatus.

2. The non-transitory computer-readable recording medium according to claim 1 , wherein

the installer program further causes the computer to, if any document data remains in the document box to be deleted, move the remaining document data to the document box created in the image forming apparatus assigned to the target group.

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

control the image forming apparatus having created the document box to acquire a document box setting determined for the target group from the server; and

apply the document box setting to the created document box.
