Landscape is Portrait sideways :>D
Normally you have to tell the program (Quickbooks) to print Landscape and then you tell the Printer in Properties to print Landscape.
I just had the same in Publisher to a Canon MFP MG1720.
From the QuickBooks File menu, select Printer Setup. Click the Form Name drop-down and choose Report. Click the Options button next to the Printer name field to open your printer properties window. Go to the Finishing tab and in the Orientation section, select Portrait or Landscape
