What do the lines through some devices mean? The nature of MarkVision Professional is such that all tasks are available all of the time. However, it is possible to choose devices that do not support a given task. For example, not all printers can report their toner/ink levels. When this occurs, the name of the device that is incapable of the selected task has a line through it, as illustrated in the examples below.

When a device that does not support the current task is selected, MarkVision Professional (MVP) responds as follows:
- When a single device is selected, the message Device Incapable of Task is displayed.
- When multiple devices are selected and one or more of these devices do not support the current task, the following occurs:
Read-only tasks (such as status and toner levels): MVP displays the Device Incapable of Task message in place of the task information for that device. All supported devices have their appropriate information displayed.
Multi-device configuration tasks: MVP warns you that some of the devices will not be affected by the task because they do not support the function or feature that is being configured.
