Compare with laser printers. Similar objections.
I imagine when the 'printer head' becomes an integrated circuit, and the materials become the equivalent of toner cartridges, we'll see rapid adoption.
Home laser printers haven't replaced books, magazines, or professional marketing materials like brochures or flyers. The same way that 3D printing won't replace factory manufacturing.
Yet home laser printers have their place. They are ubiquitous. They are useful. They replaced entire classes of professional (typists, copyeditors, pasteup artists).
