wine users - Apr 2009 - File access denied when printing from a Delphi application

Hello, everybody!

I'm getting the following error when I'm trying to print from a Delphi
application:

File access denied.

This printer routine in my application is a routine to print text. So it prints
to a file
in LPT1 . The source code is more or less like this:


Code:
procedure Print;
var
  File: TextFile;
begin
  AssignFile(File, 'LPT1');
  Rewrite(File);
  try
    Writeln(File, '...');
    // ...
  finally
    CloseFile(File);
  end;
end;



I think the error occur in the AssignFile or Rewrite procedures, when the
application tries to generate the file that will hold the printing on the
system. I'm almost sure that if I execute my application on Wine under root
or superuser the printing will work, but we all know that we should not execute
applications on Wine like that. So what's the solution to have file access
in this case?

Thank you.

Make sure you can write to /dev/lp0

Code:
man usermod

Like this, for example:


Code:
usermod -a -G lp marcos

vitamin wrote:

When I execute the command:


Code:
usermod -a -G lp marcos



I get the message:


Code:
usermod : unable to lock password file



How can I solve this?

-> You need root privileges for adding users to group.
-> You can use the sudo command for executing a command with root privileges:


Code:
sudo usermod -a -G lp marcos



I hope this helps,
