Implement print preview tab controller.

For print preview, a PP tab should be linked with the tab that initiated the printing operation. If the tab initiates a second printing operation while the first print preview tab is still open, that PP tab should be focused/activated. There may be more than one PP tab open.

Hook ctrl+p to show print preview tab.
