Use Library Tech: Large-Scale Printing & Scanning

Large-Scale Printing & Scanning

The Library TechHub can provide access to large format printing and scanning.
These services are available to all current Caltech students, staff, faculty, and postdocs.


Before sending a file to Library staff for printing, please be aware of the following:

  • As of April 1, 2024, prints are charged at $8.50/linear foot, oriented to minimize length

  • A​​​​​ valid Access account and PTA or UID are required for billing purposes

  • When possible, create your document at the desired print size, rather than relying on scaling.

  • If scaling is required please use consistent measurements when noting expected Height and Width dimensions, or give the most important measurement if the second is flexible (ex: 46"x36," or 42 inches High)

  • Our 36" wide paper roll has a maximum printable width of 35.6"

    • White space in the margins to either side of the 36" dimension may be clipped with no change in overall image size, otherwise a 1% reduction in scaling may be applied

Please fill in the Large Format Print Request when your file is ready.


Maps and other large sheet scanning can be done on our 42" wide format scanner, located in the TechHub office in Caltech Hal Rm 109.

Staff can assist you with the scanning process, and the resulting files can either be saved to your portable storage device or shared with you via Box.

For items that cannot be run through a feeder, use the large format flatbed scanner in the Geology Map Room, 207 N. Mudd.

Please contact Library staff if you need to arrange access.
