I use a Laserwriter IINTX, and it seems that for straight text, the limiting factor is the print engine speed. However, when I download 900K plot files to it, it takes forever to send it at 9600 baud (I'm going to see if my workstation will reliably send at higher baud rates). I've noticed that several computationally intense postscript demos that have warnings in them that a printer timeout may occur run fast with no timeout on my printer, because the IINTX has a very fast processor in it. I suspect the bottleneck is the serial transfer. I'll attempt to speed up the baud rate and report if that is indeed the problem. Yes, 900K files are a bit excessive, but I do cartography with it, and there's just lots of little vectors. -- ben@epmooch.UUCP ben%servalan.UUCP@uokmax.ecn.uoknor.edu {chinet,uokmax}!servalan!epmooch!ben (Ben Mesander) War in gulf: newpath 288 396 216 0 360 arc 288 612 moveto 288 180 lineto 288 396 moveto 136 244 lineto 288 396 moveto 440 244 lineto 36 setlinewidth stroke showpage
