Using the Microsoft Generic Text Only printer driver in vista.. need help configuring it...

hi guys, i got a dell a920 with vista rtm installed. i tired using the drivers that cmae with the printer.. but it doesn't communicate with the printer... so i decied to try the genirc ones... i'm following this guide:
http://www.frogmorecs.com/arts/using-the-generic-driver.html

and i'm too part where it says:

"The next tab in the printer properties allows you to setup a hand full of printer escape sequences, to configure this you will need some information from the manufacturer of your printer on the printers language. For this example I have just entered some simple Hewlett Packard laser printer commands to select landscape at the start of the job and to reset the printer at the end. Usually printer commands start with an escape character, you can enter this character using the sequence 1B> instead."

heres picture of the info i need:
