I have seen various postings about this error, where you get a javascript error quoting a problem with - res://C:\WINDOWS\SYSTEM\SHDOCLC.DLL/preview.dlg We have a customer who is getting this and also says the error is stating - "line 1344 char 1 error invalid procedure or argument code" all other discussions on this topic refer to different line numbers to this one, but nevertheless I have got him to try all the suggested fixes, without any luck. The really odd thing though is that he says he only gets the problem when printing from one particular website, all other sites and email printing are ok. Anybody out there got any ideas/suggestions? Many thanks in advance. Tony

Thanks for that, but that is one of the options we have already tried. That reports an error on line 1210 "Unspecified error", whereas we are getting "line 1344 char 1 error invalid procedure or argument code". Nevertheless we tried it without success. I just can't understand why it is only on one particular site it happens on..... Tony
