This worked for me:
a) Establish how many cols your printer can do - put a couple of lines at the top:
123456789012345678901234567890123456 <units> etc etc 0 1 2 3 <tens> etc
b) then print that just that first page
then go to the last character in the line and press SHIFT+ALT+ Left click
and drag down and to the left to the end of your document- this does a rectangular select.
Ctrl+C and then create a new document and paste in there - all the lines are truncated and should now print fine.
