Just got an email from OS Maps,
Hi ______
Sorry to hear of your reported issue printing from the new os explore site.
A fix went into the browser version on wednesday 16th which has resolved most printing issues. I am suprised therefore to see your email of 19th; can you please provide details of the device, the browser used and the date you used the site last? This will assist in researching what has happened in your case.
I look forward to hearing from you.
So at least they are looking into it. I have printed the same map into PDF from both sites and will send them the copies. Hopefully if enough of us complain/review the new site they will change it. As the new app works a lot better than the old one did. Shame if they don't change, as being able to print out a copy of my route is very helpful and of course is silly to go anywhere without a paper map.
What I have noticed is that with the A3 print from the old website as it is to scale (4cm a square) I fit less map on by about 1/4 of a square compared to the new print (3.65cm a square). Even though physically there is less map on the A3 page as it has a significantly bigger border.
The new OS maps page will print out an extra page with the date and what browser I used for some reason with nothing else on it.
