I am making some labels which I need to be a specific size.
I have set up a table 3 columns and 4 rows - each column 7.3cms wide
and each row 3.5cms high - this being the size of each label I need.

I then mail-merge from an Excel spreadsheet the details of each
label.

When I print the labels - they are not 7.3 wide - I have to make them
7.9 and then they will print as 7.3.

I am using A4 size card - landscape - HP Laserjet 5mp - nothing
unusual.

There is some sort of scaling somewhere - any ideas?
