In fact i have :-) I've made a correct reading but a wrongfull writing. The measures were X=3,975 in Y=3,999 in so we are not to far from 4 in But if I try to insert 3,975 or 3,999 in the form, it calculate a ratio of 2, in fact for any data I insert that is above 2 it insert 2. But if i've understood the correct ratio should be: 3.975/4 = 0,993 3,999/4 = 0,999 Alle mercoledì 28 novembre 2007, DJ Delorie ha scritto: > > > i was trying to calibrate my printer, so i measure the X and Y lines > > with a caliper and i get x=3,975 in Y=4,999 in (if i've read > > correctly my caliper :-)) > > Hopefully, you haven't.
