(That's what Brandon meant by being a page | printer.) Once the paper starts, you have to feed the image to the | printer on time, otherwise you would get gaps. | | One easy way to do this is to build the page image in memory; then you are | assured that the image is available when needed. But you can also create | the image in bands, provided the next band is available when needed. +--------------- How do you convince the LaserJet to start printing before the entire page is in memory (that is, without sending it a formfeed command)? I'm not needling; I can think of a few programs I've used on other systems which could benefit greatly if I could teach them this trick... and I've not seen anything in the LJ-II technical reference saying that this could be done, or how. ++Brandon -- Brandon S.
