Video card problems. Since BandLab uses OpenGL library, you may encounter problems with old video cards which do not directly support OpenGL calls. Some video cards drivers have problems with Windows 2000 operating systems. Most common bug is that the half of the Scene window remains black. Try to resize window from bottom to top to minimize it and then resize back. This usually invalidates the whole window area and removes black part. Another problem may be seen when exporting the image into bitmap. If window is too small the image may not be exported. Try to enlarge the window to work around this bug. Checking for a novel driver from video card manufacturer sometimes is not very helpful. When installed, these drivers may not work at all or crash the software. Check back with more older version of the driver or try to use the driver provided by Microsoft.

Printing features. You can always print your image into 24-bit bitmap file and then redirect it to printer. Note that Windows MSPAINT program is used for these operations. Standardly when installing Windows operating system, this program is installed automatically. If custom installation was chosen, this program may be not installed on your computer. Use Windows setup to install MSPAINT program in this case.

Direct printing as implemented by Windows includes metafile spooling. You will NOT be able to print directly your images under Windows 9X/ME since metafile spooling is still not implemented on these operating systems. Metafiles are implemented under NT/2K operating systems so you can in principle use these features to print your images if printer drivers are compatible with the OpenGL drawing instructions. We however must admit that this kind of development is still in its infant phase and very few printers may support these options. All of this does not apply to printing 2D graphics since Windows GDI is used instead of OpenGL.
