I have seen some cases of this; it seems to vary with a number of things:
-- the printer or printer driver
-- The setting under Control Panel / Regional Settings / Advanced / Language for non-unicode programs (Seelct English - United States)
-- The setting under Control Panel / Display / Settings / Advanced / DPI setting (shouod be Normal, not large fonts)

In one case, I had to selct the MICR fields at the bottom of the cheque and use the arrow key to move them down until they almost "dispappeared" behind the bar at the bottom. You'll have to experiment: go down too far and Windows may trigger another page.
