I am consider a HP Designjet 5500 printer which takes up to a 60" roll. I intend to do plots that exceed what I understand to be Adobe PDF length limits (129"?). I will be plotting from AutoCAD 2005 some large banners that are very heavy in text, mostly Arial font. Some drawings are up to 60 mbytes in size. I' ve seen samples from this plotter and can easily read such text at some 0.04" text height (not that I need this small text but I will be frequently plotting to 0.06"). I can buy, for close to a 00 extra, the Postscript capability. But why should I even consider it? I don't want to muddy the waters with this post but do want to bring up the thermal vs. piezo issue. HP uses thermal and competitors, piezo. Is piezo something I should consider in something other than HP? Any tips? Len Miller
