Opening a pdf document and trying to print it results in the computer shutting down. I am using Adobe reader 9, printer is a Samsung CPL-300 colour laser.
I've uninstalled and reinstalled Adobe reader, used system restore to go back several days, uninstalled and reinstalled the printer, downloaded latest printer firmware, changed the USB cable. All to no avail.
The problem first appeared when I tried to print a manual from a newly installed external hard disc - a LaCie 1 terrabyte.
The printer works O.K. when printing from Word or Exel etc.
Sorry about the delay but I've got hold of another printer with exactly the same result. The external hard disc was disconnected immediately after the problem arose. I am at a total loss as to the cause or cure and would appreciate any help I can get. Thank you.
