Detect installed printer?

[newengland]

Can I / how can I detect whether a particular printer has been installed? I know the exact name of the printer.

Any help would be greatly appreciated - thanks.

I don't know if it will work on non-NT system but I think that you can try this:

result = Registry.GetKeyNames(HKEY_LOCAL_MACHINE, "\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Print\\Printers");
result = Dialog.Message("Notice", result[1], MB_OK, MB_ICONINFORMATION, MB_DEFBUTTON1);

It will enumerate all printers on your computer (my example only show the first)

Good one Eliminator.

We do not have a direct action to do this. I'll bet that there is a key somewhere on non NT machines in the registry.

Thanks for your help.

In XP and 2000, the registry location is different:

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\Current Version\Devices

We decided to instead go with a script that uses the Windows FileOpen function. See http://msdn2.microsoft.com/en-us/library/ms536027.aspx

Sorry, I didn't check on other but you can use a System.GetOSName and for each os use a different key.

Sorry for my mistake

How would I handle the error if no printer is installed?

Getting quite frustrated, can I even suppress the error?

Any help please... All i need to do is detect whether or not a printer is installed, but I get "a nil value" if no printer is found.

FOR NT

result = Registry.GetKeyNames(HKEY_LOCAL_MACHINE, "\\SOFTWARE\\Microsoft\\Windows NT\\CurrentVersion\\Print\\Printers");
if result == "" then
~SETUP YOUR ACTION FOR NO PRINTER HERE
else
~SETUP YOUR ACTION FOR YES PRINTER HERE
end

FOR NON NT

result = Registry.GetKeyNames(HKEY_CURRENT_USER "\Software\Microsoft\Windows NT\Current Version\Devices\\Printers");
if result == "" then
~SETUP YOUR ACTION FOR NO PRINTER HERE
else
~SETUP YOUR ACTION FOR YES PRINTER HERE
end
