Các bạn đã cài đặt driver máy in (Canon / HP / EPSON/ Samsung / Brother ,... hay bất kỳ hàng nào khác ) lên trên hệ điều hành Windows XP / Win 7 (32/64 bit)/... . Bạn muốn thực hiện chia sẽ máy in trong mạng nội bộ (LAN) nhưng không thể kết nối được . Khi đó một thông báo lỗi như sau xuất hiện trên màn hình máy tính “Windows cannot connect to printer" và kèm theo là mã lỗi (0x0000007e) như hình bên dưới :

Lỗi là do trong quá trình chia sẽ máy in trên máy B , đường dẫn vào thư mục driver máy in chia sẽ đã bị thay đổi, quá trình copy driver từ máy B sang máy A không thực hiện được. Có 2 cách khắc phục lỗi này như sau:

Cách 1: Xóa khóa BIDI trong registry của máy B (phải sao lưu registry trước khi thực hiện):

- Vào Start\Run gõ: Regedit, sau đó tìm khoá theo đường dẫn:
KEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Printer\printername\CopyFiles
chọn key BIDI và xóa đi.

Cách 2: Chép file hệ thống trên máy B:

- Vào thư mục C:\Windows\system32\ chọn file có tên "mscms.dll"
- Sao chép tập tin này vào thư mục:
[JUSTIFY]+ C:\Windows\system32\spool\drivers\x64\3\ nếu đang sử dụng Windows 7 64-bit .
+ C:\windows\system32\spool\drivers\w32x86\3\ nếu đang sử dụng Windows 7 32-bit.

- Sau đó thực hiện cài đặt máy in chia sẽ trên máy A như bình thường, quá trình cài đặt sẽ thành công.

- Lỗi này rất hay gặp phải trên các máy window 7, không phụ thuộc vào loại máy in và driver sử dụng.

không thể cài đặt máy in!!

Step 1: Start the computer in safe mode Start the computer in safe mode in order to remove spool files. To do this, follow these steps:

Restart your computer and press the F8 key repeatedly while the computer is starting. On a computer that is configured to run multiple operating systems, press the F8 key when the Boot menu appears.
Select Safe Mode when the Windows Advanced Options menu appears, and then press ENTER.
If the Boot menu appears again and you are prompted to select an operating system, use the arrow keys to select the operating system, and then press ENTER.

Note For more information about how to start your computer in safe mode, click Start, click Help and Support, type
safe mode in the Search box, press ENTER, and then click the Start Windows in safe mode topic.

Step 2: Delete the spool printer and driver files In safe mode, delete the spool printer and driver files. To do this, start Microsoft Windows Explorer, and then delete all the files and the folders in the following two folders (where C: is the drive where Windows XP is installed):

C:\Windows\System32\Spool\Printers
C:\Windows\System32\Spool\Drivers\w32x86

Step 3: Edit the registry Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk. First, remove the Windows NT subkeys Remove the potentially problematic registry entries for Windows NT x86 service subkeys. These may have been installed by third-party printer setup programs and may be interfering with the print spool service. Follow these steps to keep the drivers, print spools, and registry entries that were included with Windows and to remove all other drivers, print spools, and registry entries that may be causing issues.

Start Registry Editor. To do this, click Start, click Run, type
regedit in the Open box, and then click OK.
Locate and expand the following registry key to view the list of subkeys (subfolders):

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environments\Windows NT x86 In the subkey list, there should only be the following subkeys:

Drivers
Print Processors
1. If there are any subkeys other than the subkeys that are listed in step 2, follow these steps:
  1. On the File menu, click Export.
  2. In the File Name box, type the name that you want to use for this key, such as
    WindowsNTx86regkey, and then click Save.
    
    You can use this backup of the

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environments\Windows NT x86 registry key to restore the key if you experience any issues after you complete this procedure.

Delete all the subkeys other than the subkeys that are listed in step 2. To do this, right-click each subkey that is not displayed on the list, and then click Delete. Click Yes when you are prompted to confirm the deletion.

Second, remove registry entries for the default print monitors Remove the potentially problematic print monitor subkeys that may be interfering with the printer that you want to use. These may have been installed by third-party printer setup programs. Follow these steps to keep the print monitors and registry entries that were included with Windows and to remove all other print monitors and registry entries that may be causing issues.

Start Registry Editor if it is not already open. To do this, click Start, click Run, type
regedit in the Open box, and then click OK.
Locate and then expand the following registry key to view the list of subkeys:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors In the list of subkeys, there should only be the following subkeys for the default print monitors:

BJ Language Monitor
Local Port
PJL Language Monitor
Standard TCP/IP Port
USB Monitor
1. If there are any subkeys other than the subkeys that are listed in step 2, follow these steps:
2. On the File menu, click Export.
  1. In the File Name box, type the name that you want to use for this key, such as
    Monitorsx86regkey, and then click Save.
  2. You can use this backup of the

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors registry key to restore the key if you experience any issues after you complete this procedure.

Delete all the subkeys other than the subkeys that are listed in step 2. To do this, right-click each subkey that is not displayed on the list, and then click Delete. Click Yes when you are prompted to confirm the deletion.
1. Exit Registry Editor.
2. If a printer is attached to the computer, disconnect the printer cable from the computer, and then restart the computer.

Step 4: Install the printer and print a test page
Reconnect the printer cable to the computer, install the printer according to the manufacturer’s instructions, and then try to print a test page.
