I like to print up my planned rail trips before my trip - then use them when I purchase my tickets or plan day trips. Lately I have been having repeated difficulty printing out the info from the German rail site - anyone else having these problems? A page will usually print out but it is often blank with only a small heading at the top.

Sounds like it might have to do with the 'frames' on the webpage.
One way to be sure is to drag cursor over all the areas you want to see (so they're highlighted), then
-file
-print
-selection
-ok

As well as above it could be that DB protect the timetables so you can't print them off.

But follow the rpevious suggestion but first see if you can cut & paste it into a word document - save some paper, save some ink, save the world

I've had no problem printing them today and yesterday, lots...
I use the link on the home page of www.budgeteuropetravel.com which has a link to the German English schedule page and it always works after i click on the link.
But when i go to bahn site directly it doesn't always work... so i don't know why there would be any difference but try the budgeteurope link and see.

Thanks for the suggestion - I have used this site and method for several years now and never had any trouble until about the last month - trying to plan for my upcoming Italy trip.

On the German Rail site, when you get to the results page, there is a small button in the lower right which reads "Print view" in the English version or "Druckansicht" in the German. This will give you a "printer friendly" page without frames, which should print out better.

Musicteacher makes a good point - especially so as on some computers like mine the print button is out of sight unless you scroll the page over to it so you may never have known that it's there - way down in the bottom right corner.
