I recently upgraded from Outlook 2003 to Outlook 2007.  Calendars printed in
Outlook 2003 had very crisp grid lines and printed color-coded categories if
desired.  It was easy to read.  I'm not finding the same to be true in
Outlook 2007.  Events that cover a block of time (say an hour or more) are
not clear to read, grid lines disappear, colored categories don't print
colors -- just black and white -- it's difficult to look at the calendar and
determine when events start and end.  

I'm using the same printer, a HP Photosmart C6180.  I've tried various
settings in Page Setup.  I've changed my printer preferences.  But I'm not
seeing any changes. I'm at a loss as to where to look next.  I've tried
looking at the Microsoft Online Training and Demos and nothing addresses the
issues I'm having.  I don't know if my problems are with Outlook 2007 or with
my printer or with the two of them "talking to one another".  I lean towards
Outlook 2007 because I didn't have these issues with Outlook 2003.

Any ideas or help would be greatly appreciated.

Thank you,
Peg
