Windows – How to connect Windows 7 64-bit to shared HP LaserJet 1000 printer installed on Windows XP

This is basically a 32-bits/64-bits problem: The printer is on a 32-bits server and is being accessed by a 64-bits client. Any attempt to install this printer fails because the driver being offered by the 32-bits print server is incorrect, since it's offering a 32-bit driver.

See this article for installing 64-bits drivers on the client machine:
How to Install HP Printer Drivers In Windows 7 - Inbuilt Drivers

The idea is to install a fictional printer on Windows 7 using the correct 64-bits driver, then convert it to a network printer. You should proceed as follows:

1. Install 64-bit printer driver for the client machine, as in the above link, as a local (not network) printer. If, during installation, you are prompted to connect the printer to your computer, choose the option to proceed with installation without connecting the printer. Install to LPT1 (default) only. (port change is done after install completes in Steps 5 & 6)
2. After installation completes, open the Printers applet from the Windows 7 Control Panel.
3. Right-click on the new printer and choose Properties.
4. Go to the Ports tab.
5. Click Add Port…, select Local Port, then click New Port…
6. For the port name, enter exactly the network path and share name of your printer. For example \\Windows2000\HP LaserJet 5Si, Click OK, and double-check that this new port is selected with the checkbox next to it.
7. Click OK to close the printer properties.

The above was written with a Vista machine in mind, so please adapt the procedure to Win7 wherever necessary.

Take a look at this tutorial which explains how to use the Microsoft Management Console (MMC), to remove unwanted printer driver packages.

If that does not work for you, try using the printui.exe tool.

In an admin elevated command prompt type printui /s /t2, be sure to remove the driver AND the package.

Here's how to do it, step-by-step:

1. Open a command line with administrative rights: Start->All Programs->Accessories->Command prompt; Right click -> Run As Administrator
2. Run the printui tool: printui /s /t2
3. Try deleting the printers. If that doesn't work... (i.e., if removing the printers listed in the printui is not successful.)
4. Click Start > Run > Services.msc
5. Locate the Print Spooler service, and right-click > Properties > stop service.
6. Open My Computer and browse to C:\Windows\System32\spool\Printers (you will need to click "OK" to get access to the folder).
7. DELETE the contents of the folder you opened in step 6.
8. Go back to services.msc and Restart the Print Spooler service.
9. Go back into the printui utility (you might need to restart it using same method as above) and try removing printers again. This time it should work. If necessary, check the "Ports" tab and remove any TCP/IP ports that are associated with the old printer.
10. Last but not least, check other computers on your home network to see if any of those map to the old printer, and remove these mappings
