"Johann Gensfleisch zur Laden zum Gutenberg".

Oh, if he could see us now with our laser and inkjet printers. Actually, his techniques were in use until the 20th century. His big contribution was to develop a superior method of producing small metal type with a single letter on it, which was much more practical than carving complete wooded blocks. His idea made the printing of text a lot cheaper and easy to produce. So the modern computer printer should be well thought of and it is really amazing. Thanks, again Johnny. You can now look over the printers from Amazon. In fact I recently got a new printer (on black friday) which saved me about $75. You can check other prices with Amazon but I think Amazon has some good deals. BTW, my printer is a HP ENVY 7643 - and setting it up as a wireless printer was done with little grief. Also, you can look at some 3D-Printers shown on left side (bottom). You may have to do some research for 3d printers as it appears that you may need some accessory aids. Since I have no experience with 3d printers, but I'll bet it will provide a new toy for computer users that will keep you busy.
