Print on Green Bar

WE are going to have to replace some Line printers
(dot matrix) they use Green bar paper I tink 14 x 17 and my boss wants me to find out how we can use them to print Excell reports. I have tried to use a custom paper setup but cannot get it to fill the paper. We have one user that uses a HP 1220c and is able to use single sheets by picking Tabloid paper. I don’t have any choice like that.
Is there any way I can get these to work.
