printing problem

[Bonez]

I have an HP iii printer attached to my system which is running caldera 
2.4.2. Printing works, but often when printing from a linux app, a la 
OpenOffice, I select the US LETTER paper size, hit print and the OnLine light 
goes off, requiring me to hit the Continue button, which then motivates the 
printer to spit out the page. 

Often when I first open OpenOffice and create a new document, the default 
page size is A4. I wish I could make OO default instead to US Letter. Any 
suggestions on these questions?
