Settings to print on HP Deskjet 5150

I am running MacOsX Leopard with two printers. the deskjet is for printing ordinary docs and I have a photoprinter for colour photographs.
When printing some instructions recently I am unable to select any paper except Photo paper. Plain paper is greyed out. I can select draft and less ink etc but am still getting better quality than I need for the task. Obviously I do not need so much ink to be used.
It is frustrating that the menus are there but not functioning.
