Print From Webservice

[guxiyou]

I've seen many posts asking how to print from a webservice. However, I've never seen a clear example / how-to or even set of instructions on how to do it. Has anyone seen something like this? I am trying to create a webservice that prints rtf documents (would only be used on a LAN, it obviously wouldn't be available over the internet). I'm trying to do this in C#. Is this possible? Are there any resources that any of you know about to accomplish this task?

Have you looked at the PrintDocument class?
Also, I *think* if the RTF filetype is registered with the system (like you can right click on it and say "print" ) you can do something with the Process class, to just have it print using the program configured to normally handle RTF documents.

I agree that the Process class should be helpful, but I don't think it works without a User Profile. When the Process command executes from the webservice will there be a default printer? When it executes will the system know that there is a program configured to handle rtf documents?

Good point, did not even think of that. I suppose that is the reason you do not have access to the printers ?

That is my only guess. I've setup impersonation: I know that I have sufficient security. I've checked that the printer is installed (I created a log file and printed out the list of all installed printers). I even have gone so far as to allow anon-users to print on the printer. I've verified that my code works when it is NOT in a webservice and it seems to work just fine. Nothing... I always get an error stating that "Settings to access printer 'printer name' are not valid"

Is there anywhere in the code that that you rely on like "default" settings(whether you know it or not?)? Maybe they just don't exist and that is the problem?
