Not necessarily. If you have a long enough room and an enlarger with a tilting head (think Beseler 23c and its ilk), you can project onto a vacuum easel (or wall-hanging sensitized canvas) by switching the enlarger to horizontal mode. I've considered doing that myself, though I don't quite have the fiscal capacity to experiment with it. Alignment's probably a bear, though.
