If a designer works beyond screens and layouts reach the physical world, it makes sense to buy the simplest, cheapest printer. Inkjet models are affordable.
Any layout — business card, invitation, certificate, presentation page, menu sheet — should be printed in the end. Cut away margins, or tape several A4 sheets together if the format is larger.
Paper always looks different from the screen. Type is too small, the logo sits too close to the edge, details vanish in low print contrast. Errors appear that the eye never caught on screen.
