Re: [SLE] Direct Printing in LPRng

Thank u for your respose Mr. Meixner. I will try the HOWTO document.
This is my scenario, We have linux client (lpd service running) connected to
the remote server (Windows). An lpr printer was created at the windows
server from there we are trying to print large documents (some 200 Page).
Since printer is created at the server, filtering is done at the lpd of the
server. Then the lpd running at the client stores the entire document but we
have limited free space (6 MB) hence printing of larger document (in our
case approx. 25 page MS word document).

If the lpd at the client is capable of getting the job in a phased
manner or if it could print while spooling we could print large documents.
If u have any idea pls suggest me.
