Hello,
Hopefully by now you figured it out. If not, you can use plain papers in the unit. You just select plain paper in the print dialog box. I would avoid using plain paper that is not of a heavier weight than standard paper. I use at least 24-pound paper. I assume you are using large format paper. 13 x 19 is readily available. Hammermill is a decent choice and I think in that size it is a 28-pound paper. 17 x 22 is going to be a lot tougher to find in a plain paper. You are going to end up with presentation paper that gets kind of expensive for blueprints. Most cost effective is going to probably be Graytex Papers, it is called Engineering Paper size C, about $50 for 100 sheets. Bond plotter paper, non-glossy, is the description. I used to do a lot of glue up of larger printed pads for dispatching and such, that was my paper source. Good quality papers made in the USA. Your setting is going to be plain paper. Hopefully that helps.
