Do you know if that is the Windows Courier New, one of the MS TT Core 
Fonts package, or one of the X aliases Liberation Mono, Cousine, 
Cumberland, Cumberland AMT?

See:

$ cd /usr/share/fonts/
$ ls -glo {truetype/msttcore,win-}fonts/Cour*.ttf | cut -c35-
truetype/msttcorefonts/cour.ttf -> Courier_New.ttf
truetype/msttcorefonts/courb.ttf -> Courier_New_Bold.ttf
truetype/msttcorefonts/courbd.ttf -> Courier_New_Bold.ttf
truetype/msttcorefonts/courbi.ttf -> Courier_New_Bold_Italic.ttf
truetype/msttcorefonts/couri.ttf -> Courier_New_Italic.ttf
truetype/msttcorefonts/courz.ttf -> Courier_New_Bold_Italic.ttf
