It's probably just a simple thing, but is there a utility which allows you to print with the image at say 50%? I've used epsom, HP and Lexmark and none of these allow any control over reducing or enlarging (unless i'm missing something). How I miss the Mac's where this was just taken for granted.
I have a HP Photosmart 7550 and the HP "Print & Document Director" software certainly allows u to specify the % u want to have a document at as standard. However, this printer wasn't one of the cheapest lol! I don't know about other printer software.
U could try downloading image software as this will often allow u to resize documents by a specified %.., try some of the free downloadable image software. I can't specify a particular one as it is down to personal taste which one u like using but if u do a general search thru google for 'free downloadable image software' u should get quite a few choices. Some people like Ulead which is often on magazine discs, I use PaintShop Pro and love it, but it is only available on a time limited free trial and then u have to pay for it.
