If you have Adobe Acrobat, you can do this (in OS 10.6.8 and iCal 4.0.4): Save the month as a PDF file. Open it in Acrobat and go to File/Print. With the Print dialogue box open, click on the down-pointing triangle (sometimes called a "Delta") to the right of the printer name. Look for a Check box that says "Auto-Rotate and Center". Remove the check in this box. The format will default to vertical. Be warned, the print is tiny! This work-around does not re-scale the document.
