To follow up. I determined the page numbers were not added by CUPS, but
by QtextDocument which is the default. Also, by default QtextDocument
sets the margins to 20mm all around. By adding a few lines like this in
the checkprinting.cpp plugin file the problem is resolved:

QSizeF ltr(612,792);               
htmlPart->setPageSize(ltr);         //set page to US letter size
htmlPart->setDocumentMargin(10);   

This reduces the margins and gives plenty of room to properly print a
check. Setting the PageSize gets rid of the auto page numbering that
QtextDocument defaults to. 

Can you let me know what I need to do to ask that these changes or
similar get in the plugin?

thanks
