About printer driver question

Hi All,

I want to know the limitation about the paper size and resolution in print driver for 32b and 64b System, Would you please tell me that.

For example, Is it possible if the paper size is more than 100 x 100 inch and resolution more than 600 DPI by Unidrv,
It is about 3.43G dots for one page for this paper, It takes more than 10G memory for 32bits bitmap.

For very large paper sizes you will probably have to use a
device-managed surface and not actually allocate the memory.

Banding may be a solution also but I’ve never done that.

I don’t know what the maximum size bitmap a printer driver could
allocate is. Win 7 fails if it’s bigger than 4GB but you can work
around it.
