i am running redhat 9 pluged into a canon s820 printer via parallel port

when it prints it only uses a quater of the page, ie what i what to print is very small in one corner

i have tried to change the resolution, no change, i have changed the font to massive but it only prints in the same quater of the page, i have changed the page size from A1 to postage stamp and it still does the same

what can i do to get normal printing

i do not want to have to put my HP back in as there in no ink left in it!!
