There was some discussion awhile back on this forum that touched on this subject. One person was able to accomplish this by first setting up his printer for banner paper and landscape. The when preparing the chart in UFTree, he once again had to set up for landscape by clicking on ?gpage?h in the setup screen and then landscape. He also stated that you must use ?gwall chart?h and not ?gbook chart?h to make it work. Another tip ?c make sure headers and footers are not selected, as they print at the 8-1/2?? end of the chart.
The extra spaces ever 12" or so might be where the "Book Tit'le" option has been set. This leaves space as part of the header on every page of the report. You might want to click off on that option. There were also some tips awhile back about the extra white space at the top of pages on regular reports. Does anyone recall if there was a solution for this?
