Later printers, yes. The origin of the double space actually goes back to the original old block style printing presses. Different blocks were used for different sized spaces, with the largest block used to separate sentences. The reasoning was because letter blocks were the same regardless of what was around them, which creates gaps in a sentence depending on which letters are adjacent to each other. A larger space was necessary to signify the end of a sentence. Since the letter before that space was small (a "."), it created a large and unmistakable space.
The origin of the double space and the reason it became a part of writing styles are largely different. The double space predates printing presses--Gothic writings quite often used large spaces to seperate sentences (and non-Roman European writings before then often didn't use periods or spaces at all).
But, ultimately, the only reason it had been included in modern styles is because it was conducive to the typewriter--not because there was a tradition of using it. French printers actually favored a single space between lines, for instance. But once the typewriter-based styles appeared, they began to start using double spaces.
If the discussion is on why we, as modern peoples, were taught to use the double space, referencing early printing presses isn't really relevant. We don't do it out of tradition, we were taught to do it because the writing system in practice when most of us learned to type was still considering typewriters and word processors as its standard. Or, even if it wasn't standard, our teachers had learned to double-space and had not yet been told to teach the new system.
