This may only happens around Gastown in Vancouver, but my bet is that the printer drivers are not exactly the same or the printer changed.
Windows, right or wrong reformats according to the printer capabilities. An user or driver can set more margin and what fit on one setup will not on another.
You have to dig this one out.

My Excel spreadsheet with macros prints fine on my older machine under Excel 97 and Win 98, but when I try it on my new machine under Excel 2000 and Win XP, the one page document is split and the bottom half will only come out as page 2. Any suggestions on correcting this?
