I am writing specifically to Mr. Zakharenkov Alexey - you showed an old printing press on TV, with iron letters (that is, letters) that disintegrate when printing, immediately after printing - one page... It became interesting to me that there is so little wood in the country from which to make, suitable in size, retaining strips, and even whole frames where these letters can be inserted so that they do not fall apart.??? I have subscribed to you in VK, I am waiting for a response.
