==Printer Disassembly==
*Disassembled printer casing
*Installed cygwin on computer for C interface and read up on programming language C
*Investigated Computer Numerical Control but found it was not useful for this application
*Investigated serial port programming and the use of Printer Control Language on an HP printer
===Parallel Port Programming===
*Interfacing directly to the printer proved very challenging
*Unsuccessfully accessed printer
*It seems one would need to write a driver to fully take over the printer in the way we desire
==Worm Gear==
*Spinning a long grooved cylinder gear requires a lot of torque
*Minimal support for head motion
*DC motor with time steps is not as effective as stepper motor
==Rail System==
*very costly
*possibly too heavy duty for this application
== Belt System ==

*We need to find something that is low cost but is accurate enough to be stopped at each fiber array block. This would call for a low pitch. One example I've found is as low as 8mm pitch with 200 teeth making a 1.6 meter timing belt. Because the intended light source for calibration is most likely going to have a wide range, 8mm is a fair sized step as the scintillators are 2mm each but grouped in blocks.
