I print patterns and plans from PS elements on my HP Designjey, T-120e printer/plotterView: original size, but can't seem to print larger than 24"x 36". Everything seems to be set correctly until the last setting, "DESTINATION PAPER SIZE" drop down menu. There is no listing of the 24" x 42" custom size I have set ?? How to set a custom Length ??Any help would be appreciated,
