Thus, you can't select everything you want to print because what you want to print consists of three distinct areas of the worksheet. This feature allows you to 'freeze' rows at the top of the screen, columns at the left of the screen, and only scroll the cells in the unfrozen part.
This simple of an approach won't work in this instance, however, because of using frozen panes. Alternately, you could choose what you want printed, define it as the print area, and then choose to print. Normally, you could simply choose what you want printed and then just print that selection. What if you only want to print just what you see on the screen, however, instead of an entire worksheet? To make matters worse, what if you are using frozen panes to hold the position of your page headers? Fortunately, that information can be easily printed out. It is easy to amass quite a bit of information in an Excel workbook.
