When I select the plot option from the file menu and select a HP Business Jet 2600 from the list of available printers as soon as that is done the egg timer appears and nothing happens, after about a minute or so AutoCAD will close, no errors are generated and nothing prints out. I have noticed that I am able to get one or two files to print, but the majority will not, but this only applies to this one printer, if I select a different printer they will print without issue. Autocad has worked fine with this printer since it was installed several months ago, this is a new problem which appeared just yesterday. Other users can print ok from AC to this printer, I used to print ok and I can print ok from other Applications. Even if I log onto the PC as another user it works fine! AC has been removed and reinstalled, service pack 1 applied but still the same. I have compared the files against each other to try and locate a possible reason why one prints and another does not, but there are no differences other than the actual drawing, besides which, all files printed ok previously. I have also ensured the print to file option is not checked. AutoCAD LT 2005 SP1 - Windows XP SP1 - HP Business Jet 2600 (networked) Any one able to help??
