short instrument names going off the page

[Jonathan Kulp]

My short instrument names go off the left side of the page. 
 I've searched the manuals and can't find the tweak or 
setting to keep this from happening.  Seems like it must be 
something in the layout block.  The full instrument names 
print normally within the printable area.  Can anyone point 
me to the right command to make the short names fit inside 
the printable area?  Thanks,

Jon
