MKI maintains a great many printers in McNair (Building 37) and NE83.  Each printer we maintain has a label with its hostname (e.g. and its internal name (e.g. 37-518 Phaser 7800GX).  LIGO’s printers in NW22 are maintained separately.

To connect your machine to a printer, either follow the instructions on the sheet by the printer (also available here), or the instructions below.

If a printer is having problems, send an email to and we will take care of it.
