HP LaserJet M2727 MFP - Software Technical Reference

To determine the latest version, compare the overall build number (in parenthesis after the model name)
and the GPD number (in the Driver Files: field). If the overall build number has increased, this is the
latest version of the printer driver.
If the overall build number is the same, check the version number of the GPD file. The printer driver that
has the highest GPD version number is the latest printer driver.
