Vista 64 bit OS says I must get a driver with a digital signature to install USB to DB25 parallel cable. The driver on the disc which came with the cable was not accepted by Vista.

1. Get a new signed driver from the adapter manufacturer.
2. Try the workarounds listed here: http://www.mydigitallife.info/2007/08/15/workaround-for-vista-cannot-load-low-level-driver-signing-issue/

For what it is worth, I generally found USB to parallel adapters worthless as most printers will not work with the adapter. Usually easier to get a new printer. If a desktop, get a parallel port expansion card.

Until a new version for 64-bit Vista comes out, there are two workarounds:
1. Boot Windows holding down the F8 key and select “Disable driver signature enforcement”. This will let you install unsigned drivers for that session.
2. Run cmd.exe as an administrator (right-click it to do this) and then type:
bcdedit -set loadoptions DDISABLE_INTEGRITY_CHECKS

Epson workforce 840 all-in-one. Driver installation fails.


Check the compatibility of the driver with the OS version:Windows 8 (32 or 64 bits), Windows 7 (32 bits or 64 bits) , Vista (32 b, 64 b), XP (32 bits , 64 bits). You should try to use the software that shipped with the printer. When installing, choose local printer (USB), or Network (Ethernet cable, or Wireless).

Install Unsigned Drivers on Windows 7 & Vista with Driver Signature Enforcement...


Every time when we try to install any hardware drivers which are not signed by microsoft, Windows shows a warning of Unsigned driver dialog box. The reason of showing warning message is to protect the stability of your Windows operating system as such drivers are not passed in Microsoft windows driver compatibility test.
In Window XP you can still install unsigned drivers but in Windows Vista SP 1 and Windows 7 Microsoft has introduced very restricted module of driver signature enforcement which doesn’t allow us to install any incompatible unsigned drivers.
If you want to bypass or disable Unsigned Driver warning message then Here is small freeware utility Driver Signature Enforcement Overrider which allows you to install and load unsigned drivers dynamically on your Windows 7 and Vista.

Supported Operating System
1. Windows Vista 32-bit & 64 bit
2. Windows 7 32-bit & 64-bit
Download Drive Signature Enforcement Overrider 1.3b
Please Note: User Account Control (UAC) must be disabled in-order to use this tool.

How to connect to computer


The unit has a parallel port interface and is supported under Windows 95/98/Me, Windows NT 4.0/2000/XP . The drivers are available here: http://www.usa.canon.com/cusa/support/office/laser_facsimile/laser_class_2050_2050p_2060_2060p/laser_class_2060p?selectedName=Specifications#DriversAndSoftware . For the supported OS versions, download the drivers and then run the exe. If it extracts drivers, note the folder in which they are stored. Then launch the Add a Printer Wizard (Printers and Faxes in XP IIRC). If your computer doesn't have a parallel port, parallel to USB adapters do exist.

Neither Vista or Win7 Compatibility Center have the unit listed. The XP driver may work in Vista 32-bit with the compatibility mode on. For Win7 or Vista 64-bit, I'd suggest a second computer, a dual boot computer or a virtual computer with an older Windows OS. For the most setups, you'll need a licensed version of the Windows OS. (Virtual computer software include: Parallels, VMWare and Virtual PC.)

With Win7 Pro or Ultimate, you can download Virtual PC and XP mode from Microsoft for free, then install them in order. The printer will install normally into the XP virtual computer. However, files from the main computer will need to go onto optical media or an external drive in order to share them with the virtual computer for printing.

I hope this helps.

I have a CanoScan LiDE80 that wont work now with my new operating system, Windows 7...when trying to install it.. says I need drivers but can't find compatiable one??? Any suggestions as I love this...


Do you have Win7 32-bit or 64-bit? If you have the 32-bit, the driver you need is here: http://www.usa.canon.com/cusa/support/consumer/scanners/canoscan_series/canoscan_lide_80#DriversAndSoftware . This driver works for Win2K-Win7. This is an unsigned driver and probably will not work in Win7 64-bit.

In my experience, Canon is very poor at supporting their scanners for 64-bit OS versions. In fact, they do not have a Vista 64-bit compatible version of the drivers for this scanner.

The only solutions I have found are tedious. 1) Keep your old computer that works with the scanner and transfer files on a USB drive or optical disc (RW is better for this). 2) Set up a virtual computer with an OS that works with the scanner. If you have Win7 Pro or Ultimate, you can do this for free. Download Microsoft's Virtual PC and the XP mode package. Install both in order. For other versions of Win7, you will need a virtualization program (Parallels, Virtual PC, VMWare) and a licensed version of XP (or other OS that will work with the scanner). Set up the virtual computer program and install the OS.

Next install your scanner to the virtual computer and use it in that "machine". You may need to transfer files to external or optical media to share the documents. You can't install a printer on both the virtual computer and the real computer at the same time (at least with XP mode).

I hope this helps.

(I tried using the compatibility mode and accepting the unsigned driver for a Win7 Home Premium 64-bit machine for a different Canon scanner. It didn't work and I have dealt with a number of old hardware and new OS issues over time.)

I ve just bought lexmark z2300 printer, how do i connect it to my laptop which is on wireless broadband with perlico? ta caroline.


You need to connect the printer with an extra cable which can join it through its 25 pin parallel cable. That cable then with USB end connect with the Laptop. and its drivers can be automatically detect by your Vista system.
For Vista 64-bit, the driver for printer and cable should be digitally signed.
Otherwise you need this method for Driver Installation in Windows Vista 64-bit:
The 64-bit version of Windows Vista is the first version of Windows that will only allow signed drivers and this restriction is built-in. For most cable drivers are unsigned and we request you to follow some prerequisites before installing the driver.
Preparing Vista 64-bit for Driver installation:
  • Using the F8 option: Press F8 key on your keyboard while booting your PC. You will get into “Advanced Boot Options”. Select “Disable Driver Signature Enforcement”
  • An F8 Advanced Boot Option introduced with Windows Vista—“Disable Driver Signature Enforcement”—is available to disable the kernel-signing enforcement only for the current boot session. This setting does not persist across boot sessions.
  • Note: Make sure to use F8 option every time you boot/reboot your PC before start working with MCS77XX.
  • Make sure that the User installing the driver must be a member of the Administrator group on the system. 
And for printer driver if you dont have CD then go through this link and follow the steps:

Let me know if you need furhter assistance, I will help you to run your Printer with Laptop.
