Look at the settings in the Print dialog for page scaling, centering etc.
Thank you for your response. Over the past few years, I always was able to register the text, and in the print dialog box I would select "Actual size" and no page scaling. For some reason, those same settings don't work the same as they used to.
You suggest I use the "centering." I can't find that in the print dialog box. Can you tell me where it is? Remember I have Adobe reader, not some higher-level Adobe product.
I have noticed something interesting when I open the Print dialog box, on the opening page. At the lower left is a button called "Page Setup..." If I click here, I see a window that looks like it could be used to specify margins, but there is no way I can change the values. Do you know how I can get access to those settings?
