The attached file, generated with the HP PCL6 driver for HP 4500 on Windows XP, prints correctly on my HP 4500DN printer but generates an "Error: IllegalAttributeDataType" message when read by Ghostpcl head (r3059+8645). The command line I"m using: main/obj/pcl6 ./test.prn
Created attachment 3950 [details] test.prn
fixed in ghostpcl 3060.
