Printing Geocaching.com Cache Pages

Currently the Geocaching.com website uses MapQuest data which is fine for the US where these maps have good coverage but for us Ozzies, particularly outside the main cities the maps are pretty useless. This Greasemonkey script replaces the MapQuest map with a much more detailed one.

Requirements

• The Firefox Browser.
  
• The GreaseMonkey add-on installed.
  
• The GeocachingAustPrint script installed.

The Script

This code will replace the MapQuest graphic when viewing Cache Pages on the Geocaching.com site when formatted for Print ie you have clicked the "Make this page print-friendly" link on the Cache Page. Install the script as filename : GeocachingAustPrint.user.js (then open with Firefox) or click here.

This is a Greasemonkey user script, see http://greasemonkey.mozdev.org/.

This substitutes the lame MapQuest map on cache printout mainly for an
OS map (where MapQuest coverage is not that good)
