A printer containing a printhead that is detachably mounted on a support plate and is held thereon at two rigid support points located on a first side of the printhead and one elastic support point located on a second side of the printhead opposite to said first side, each of the support points being defined by a first portion on the side of the printhead and a second portion on the side of the support plate, and one of the first and second portions is a spherical surface engaged in a recess of the other of the first and second portions in a self-centering manner wherein the second part of the elastic support point has its spherical surface formed by a bead or ball fixed on a wire, said wire being elastically biased toward the recess, so that the elastic support point releasably biases the printhead towards said first side of the printhead and released by lifting the wire, for detaching the printhead.
