The X1200 series uses the same driver. (X1250, 1260, 1270, etc.)

Before plugging in the USB cable you need to install printer software.

If you have the original printer disk install software from disk.

Note:some printerdoes not work on Vista, if you do not find any driver download for Vista on your model page, that means your model is not Vista compatible.

You can refer to the following link & download the drivers for your printer... i am sure it should work for you:-

http://drivers.softpedia.com/get/PRINTER/LEXMARK/LEXMARK-Printer-X125-Version-10012.shtml

The Z22 does not appear on Lexmarks vista compatability list and so there is no specific vista driver.
There is a driver for Windows XP which you could try

Select Z22 as printer model and search
then choose windows XP from the list of operating systems

I believe this will fix it for you as it did for me. I have a Lenovo laptop that updated from XP to Vista and the Lexmark 4200 X4270 All in One Printer would not print or scan. I had to do the following:
1. Delete all printers in control panel.
2. Do full update with Vista install disk
3. Make sure cable to Lexmark is not attached to Laptop until Vista does full update
4. Download the updated Lexmark Driver for whichever version of Windows you are running from the link provided below.
5.Install item in #4
6. Plug in cable to Lexmark and put the Lexmark SW installation disk in and it should finish itself for you.
