- TITLE :PRB: MS-DOS Applications Do Not Recognize Redirected LPT Ports
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:
-
- ----------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT operating system version 3.1
- - Microsoft Windows NT Advanced Server version 3.1
- ----------------------------------------------------------------------
-
- SYMPTOMS
- ========
-
- Redirected LPT ports created with Print Manager are not seen by MS-DOS
- applications. Printing to the LPT port will result in the following
- error message:
-
- The system cannot write to the specified device.
-
- The error message may vary depending on the application attempting to
- print.
-
- CAUSE
- =====
-
- Ports shared in Print Manager are not automatically translated to
- devices for Virtual MS-DOS Machines (VDM). Windows 16-bit applications
- that use standard Windows calls to print will work fine. Programs that
- try to access the port directly via a device name (LPTx) will be unable
- to print.
-
- RESOLUTION
- ==========
-
- In order to print from MS-DOS applications, use the following command
- in a VDM:
-
- NET USE LPTx \\computername\sharename
-
- This command will enable your MS-DOS applications to access your
- shared printer through the LPTx port you indicate on the command line.
- You can make the LPTx connection persistant by using the
- /PERSISTENT:YES switch when issuing the NET USE command.
-
- STATUS
- ======
-
- Microsoft has confirmed this to be a problem in Windows NT version 3.1
- and Windows NT Advanced Server version 3.1. We are researching this
- problem and will post new information here in the Microsoft Knowledge
- Base as it becomes available.
