Unable to map printer to LPT1

Hi,
My office use DOS application and shared printer. I login as administrator, use "net use" command to lpt1 and it always prompt for user and password, every time I type user password, it always failed and has an error like this:

system error 5 has occured.
Access is denied.

I tried to map to another port like LPT2 or LPT3, it success....but... When I use print command from my DOS application, it always says that "printer is not ready".

Can anybody help me, please? When I used Windows XP it's fine, it drives me crazy with this Win 7 Profesional.

Write the net use command in a txt file and save it as a .bat file on the desktop. Then right click on the .bat file, select run as administrator. It should work...

If this works, go to your UAC settings and move the scroll bar to the bottom so that you are never notified about making changed your computer. Then, move the .bat file to your startup folder and this will be mapped successfully eachtime your computer starts.

This is because DOS applications can generally only print to LPT1.

Are you logged on as a user with administrative credentials? If not then non admin users are unable to map an LPT port to to a network printer if the LPT port exists on the system as a physical parallel port.

Adding the user to local admins should get you around this.

Yes, it works. I finally can map the printer to LPT1, but, when I try to print using DOS, it still says "printer is not ready". Why?

I checked in command promt and type "net use" to see if my connection is OK, and it's fine. When I print with other application such as notepad or word it's also fine. the problem occurs only in DOS.

Yes...I use administrative credentials.

The only success I've had is to log in as the user (who has administrative privilleges) and open an elevated (right click, run as admin) command prompt windows and type in...net use lpt1 \\server\printer.

Then the user is able to print from a DOS program.

If they restart the computer, they have to rerun the net use command before printing from the DOS program.

I haven't tried turning UAC off though. I will do that right away.

have the same exact problem, i can't write a script when the user logs on since it promts for username and password which doesn't work. The user is an administrator on the local machine but the only way to make it work, is to right click and "run as administrator".... however i can't/dunno how to write that in a script
