LPR via C#?

[Guest]

I am working on an application which sends a print file to a print queue on a
sun machine. Currently this is run vit DTS and a batch file calls the LPR
command.

I am changing this app to a .net console app in C#. I was wondering if it
is possible to do call the LPR command w/o shelling out or using a batch file?

Thanks in advance,
SPO

hi,

you could use the Process class :

ProcessStartInfo si = new ProcessStartInfo();
si.FileName =
System.Configuration.ConfigurationSettings.AppSettings["path_to_exe"] ;
si.WindowStyle = ProcessWindowStyle.Hidden;
theRunningProcess = Process.Start( si );


cheers,

Do you really wat to call the LPR command directly? Why not just connect using the LPR
protocol directly?

what is currently called via a batch file is:
LPR -S <ip> -P <queue> <fileName>

I need to find a better way then that in order to catch error codes etc.

The LPR executable just calls the LPR protocol. You are using an unnecessary step. Why not just
use the LPR protocol directly. Its very simple, there are even free components to do it:

if i were to use this. Would i be able to catch a return code if the LPR app
has a error?

you could use the Process class :

ProcessStartInfo si = new ProcessStartInfo();
si.FileName =
System.Configuration.ConfigurationSettings.AppSettings["path_to_exe"] ;
si.WindowStyle = ProcessWindowStyle.Hidden;
theRunningProcess = Process.Start( si );
