Yes, don't know what you're testing for, but yes, you can test a diamond with black light.
If the diamond has natural fluorescence -- about 60% of diamonds do -- then, yes, it will glow under black light.
No, you couldn't. Printers don't scan things. _____________ Perhaps your printer scans, in which case it could use a fluorescent bulb or a bulb that contains some other gas: in any event, it is a light source. You can see a diamond's reflective quality in response to any light source, from a candle to the sun. This is not a typical test for a diamond. You're better advised to take your diamond to a gemologist who can test it and tell you whether or not the stone is a real diamond.
Diamonds both reflect and refract light. When light enters a diamond, it is refracted, or bent, due to the diamond's high refractive index. This causes the light to slow down and change direction. The light then reflects off the diamond's facets, creating the diamond's signature sparkle and brilliance.
Light entering a diamond can be reflected off its surfaces (internal or external) or refracted as it passes through the diamond due to its high refractive index. The unique internal structure of a diamond causes light to bounce off its facets multiple times, resulting in its characteristic brilliance and sparkle. White light entering a diamond can also split into its spectral colors due to the dispersion property of the diamond.
A diamond's reflective properties are due to its high refractive index. When white light enters a diamond, it undergoes dispersion, which causes the different colors of light to separate and reflect back to the observer. This dispersion is what creates the rainbow effect known as diamond fire or sparkle.
It fluorescesAnother AnswerNote that some diamonds possess florescence, some do not.A reputable jeweler with a probe will generally be able to tell you whether or not a diamond is a real diamond. A better test is to take the diamond to a certified gemologist and pay for a certificate.
An opaque white appearance under a black light may indicate that the diamond is not a true diamond but could be a simulant or synthetic stone. Natural diamonds typically do not fluoresce strongly white under ultraviolet light. It would be best to have the diamond examined by a professional gemologist for a more accurate assessment.
Yes, fake diamonds or cubic zirconia typically do not glow under a black light. Black lights are primarily used to detect fluorescence in certain materials, such as some natural gemstones or specific treatments applied to gemstones, but not in synthetic diamonds.
it will glow white, or more than likely, blue
Yes, a raw diamond will always test as a diamond.
If the diamond has natural fluorescence -- about 60% of diamonds do -- then, yes, it will glow under black light.

Yes, it is a black diamond representing a black diamond.
The test of starch by covering the black paper and keeping it into a light place at few hours.
A black diamond won't sparkle like a white diamond, but a very special black diamond, the Amsterdam Black Diamond is apparently a visually stunning stone. Read more, below.
Boart means industrial quality diamond (by nature heavlily included, near opaque), carbonado is the variety. Almost any boart can be heated to make black. There are 3 types of black diamonds, 1)Natural Black (opaque but slightly traslucent) 2)Irradiated (white, transparent, cloudy diamond, I1 to I3 clarity), can be transformed to black (opaque, slightly translucent, green traces when viewed with strong light) and finally 3)Boart diamond (60% of the diamond production). Entire diamond appear black (brownish to acerated hues), completely opaque, zero light can enter to it. From price point of view. Natural Black from 500 per carat, Irradiated Black from 150 per carat, boart heated to black from 50 per carat, so watch carefully what you`re buying.
