A Panasonic KX-P1124 24-pin dot-matrix printer is turned on and promptly begins to print one page and the beginning of a second page. Per forum request for printer sounds. Recorded using built-in mics of Zoom H4, minor adjustments made in Audacity. Somewhat noisy office environment (fan noise, mostly).
I remember I had an Apple dot matrix printer. I am still very fond of that sound. I printed out a banner for Christmas once and once for my 16th b-day back in 94 and I remember it took half an hour to print out.
