How do I lose B4 in the Word document Page setup?

My Computer--control Panel--printer and fax--blank right--add printer--"Next" (3)--epson-epson lq-1900kii--"Next" (3)--"To print test page"-No--ok

Ps:

If your printer can play B4 format document, you do not need to set, because there is already one in the printer paper option. If you want to set up, you can in the, printer and fax settings, in the File menu, select "Server Properties", click "Create New Format", enter "B4" in the table name, and in the following input B4 the width and height of the paper 25*35.5 (B4 has two dimensions, please click the actual measure), press "OK". Later use, you don't have to set, directly in Word's "paper" option to select B4.

If there is no B4 in the paper size list in the Page Setup dialog box, you can use B4 as a custom paper. To make it easy for B4 to work in all Office components, you can do the following. 1. Execute "Start/setup/Control Panel/printer and fax" commands, open the Printers and Faxes dialog box; 2. In the Printers and Faxes dialog box, click File/server properties to open the Print Server Properties dialog box, 3. In the Print Server Properties dialog box, click Format, Select the Create new format, table Name field to enter the specification data for the B4, set the paper size in the Size Description field, and then click OK after save format. This operation is done in the WinXP system.
