Custom reports created using the CU*BASE Report Builder (Query) will only print what will fit on a standard width of paper (usually 132 characters). 

 

If you cannot eliminate some of the columns, try using the "Format Columns" option to shorten the length of some the columns in your report and/or abbreviate the column headings.  Also try using the "Choose output" feature to activate the line wrapping option and/or adjust the wrapping width.
