Can anbody tell me why my HP Designjet Plotter is coming up with the message 'Out of Disk space in Drive C: data was lost. Please free up some disk space and try again'. There is 29.0Gb of free space on the disk. This appeared for the first time this morning. I have reloaded the HP software without effect. I urgently need to print for a presentation tomorrow and would appreciate it if somebody could urgently help. Thanks in advance Ian
