Parallel laser printer, IBM 4037 SE by Lexmark, likewise called ValueWriter 300 by Lexmark. I have added 4 MB of added memory (maximum this printer will certainly take). Power and parallel cables consisted of. Also user's reference and documentation (see photo). The printed output has some horizontal lines through it (see the picture). This can be dealt with by some cleaning and a little work, however I do not have time to do it. I am changing this printer with a new ink jet printer, so this printer is for sale, quite inexpensive!
