I am plotting to a Hp Designjet 1055cm plus. I am using the hpgdi8.hdi driver. when I plot anything other than a .tif image I can print once and then I have to reboot my computer to print the next one. If I try to print two images in a row it will print one and on the second one it will say it is spooling but it never goes anywhere and AutoCAD will not respond. I have to ctrl-alt-delete and reboot. it's not all images, it just seems to be the compressed image file formats that i'm having the problem with. Hopefully someone can help me.
