First, the individual computer station on every floor of the library. All computers I saw are of fairly recent vintage, have Windows XP installed, and permit use of a USB flash drive using the USB cord on the desktop that is attached to the CPU (you can see the USB flash drive in the photo below between the mouse and the keyboard):
The microfilm printer is how a user obtains an image from the microfilm on paper. You bring your microfilm (on both sprockets) from the reader to the printer area, load it on (upside down relative to what it was on the microfilm reader), and center your image (you can focus, magnify, and rotate the image), insert your print copy card, and press the print button. Each page costs 23 cents (deducted from your print copy card). There were about 10 microfilm printers on each floor with microfilms, some of them dedicated to 16 mm and 35 mm films. A typical microfilm printer station is shown below:
You can see my USB flash drive installed on the cable between the mousepad and the scanner machine. This machine has much better scrolling capability than the microfilm printer. I found that this machine was the cheapest (it's free!) and easiest to use of all of the copiers.
