I'm having a networked KX-P1121 setup via D-Link print server in my office and PCs are on WinXP OS. The problems here is when printing a custom size paper 5.5" X 9.5", it just keep on printout wrong margin setting. Is it this printer doesn't support 9.5" width as there will be second page printed. But to my understanding it should support up to 10" on width?! Any solution on this?
