We are trying to use the Mac as a word processor and wish to print
drafts on a imagewriter before sending the final to a laserwriter.  We
have found, when using A4, that the imagewriter and the laserwriter
print a different number of lines per page. We wish to alter the
imagewriter to bring it into line with the laser writer. I believe
that the Mac knows about both physical paper size and page size.
Physical page size is the size of the paper and is used to control page
feeds. This can be altered by PageSizer. The page size is the number of
lines to be printed per page. This is the quantity that we wish to
change. Is there a utility to alter the page size? If not can anybody
tell me the location of the constant used for this so we can patch it?

Thanks
Kevin

P.S. Why don't apple use the same number of lines per page on both
devices?
