Html view print has changed...

Hi, 

I have been using the Html view to create brochures using data input into our database. 

For the past year it has been printing nicely onto A4 sheets. However for some reason (without me changing any of the script) it has now changed and is appearing larger on my print version, so that the page which used to fit perfectly on an A4 page, is now printing outside of the margins, and getting cut off. 

I have tried printing from a different computer and different user account, to see if it was my computer or my personal settings which were affecting it, but the result was still the same. 

Has there been some kind of update which has caused this? Can you help? 

Thanks, Bianca.
