The memory required to operate dviout cannot be allocated.  The font resolutions, the paper size, etc. affect greatly the required memory size.

For example, when Printing by a 600 dpi printer on the A3 paper size, a minimum 8 Mbyte memory is needed for the page expansion buffer, and a minimum 8 Mbyte memory is needed for transferring BMP format data.

It is desirable to use a computer that has sufficient usable memory.  Memory consumption by other application programs also affects the performance of dviout.
