I see they have issued it since Windows 7 came out so I can't guess if this is the old issue where some one tried the driver CD that came with the printer but didn't know HP had issued newer drivers.

Since upgrading to Windows 7 Home Premium I can no longer use any of the HP Printing software that came with the HP 5280 All In One Printer which I had set up with custom paper sizes to print large panorama photo's,eg 420mm x 210mm.
I know the printer is capable of printing photo's this size as I have printed many panoramic photo's in this and similar sizes when I was running XP.
I have set some custom sizes in Print Server Properties and the settings are being saved there but they do not appear in any paper size lists in Windows or in the HP printer preferences.
This is the procedure I'm following.
1) Click start menu,then Control Panel,and finally View Devices And Printers.
2) Click printer in the list(HP 5280),then click Print Server Properties.
3) Click Create New Form,type a custom paper name in the Form Name text box and enter the desired paper size under Paper Size.Click the Save Form button,and the new form is present in the paper list.
4) Close and reopen the application.
I have done this several times and all the custom sizes I create are in the list in the print server dialogue form but none of my custom sizes appear in the paper size options in windows or in the HP printer preferences.
Am I missing something?
Is there another way to to do this?
