Designated Colleague printers default to Portrait on the Linux platform, as of February, 2018.  If you need to print a report in Landscape mode you need to Insert the following line (with quotes) in the Other Options area on the Printer Definition screen: “-o landscape”.  If you find that the content is still too large for the page, enter “-o landscape -o cpi=17 -o lpi=8” to shrink the content to fit the page.
