Allan, many thanks for your post, it certainly helped point me in the right direction. what I found though is that you do not need to tick the print as image box at any point during the setting up of this. All you need to do is add the registry key for whichever version of Adobe you are using for this to work. So basically. what you are saying for each instance of Adobe is regardless of whether or not the print as image is selected, the registry key is saying always print as image for the printer as specified by the hex code. I have found that for network printers, you have to include the full path i.e. \\<servername>\<printername> e.g \\testserver\printer1 and convert all of that to hex. With later versions (9 up over), they have allowed for the string name of the printer so that it is just plain text which also makes life easier.
What I do is apply this registry entry via Group Policy on a per room basis so that we only ever need to add one printer to the list. you could do this globally by adding all printers sequentially using s0, s1, s2 or t0, t1, t2 etc depending on which version you are using. The screenshot shows the registry key for 1 printer for Adobe Reader 8.
The value data is the binary code for the actual full printer name
This works a treat.
Hope this helps
You should be able to go to HKEY_CURRENT_USER\Software\Adobe\Acrobat Reader\10.0 From within here, crate a General key and then Create a cPrintAsImage key and then follow Allan's post above. This should work.
