124 mm x 275 mm envelope print settings

Hi 

I am using HP InkJet F4488 and LaserJet CP1525n

I am having a problem with printing envelopes on both printers. My envelopes are of 124 mm x 275 mm

LaserJet CP1525n : the printer prints the address at the bottom of envelope and some times

last 2 - 3 lines are out of the envelope.

InkJet F4488 : the printer doesn't print anything.

Can anyone please help me out.

Thanks and beat regards
