content: is there a machine that can interface with a computer and print a document on a multiaxis in a open space, so you don't have feed mechanisms and other horse shit to deal with ?I don't care if its slow.

content: You mean something that can print on (almost) arbitrary-sized media without having the media being fed through anything?Like a kind of large X-Y gantry 3D printer or CNC machine, but with, say, an inkjet print head?

content: yes or a heated bed and a laser. it can be 9.5 by 11.5I can't imagine toner working well but maybe there is some method (i.e. powdercoat)I am sick of printers fucking up transparancies. i want to make masks.

content: can it draw a mask?I assume the proper method to make a mask is to use a laser to engrave thin glass (like gorilla glass) and use some kind of ink that only sticks to roughened areas or something?

content: Yes, exists inkjets with flatbeds that use ink UV curable. They can print a PCB, a mask or something flat. Some exampleshttps://www.alibaba.com/product-detail/uv-printer-price-3d-metal-printer_62105184353.htmlhttps://www.alibaba.com/product-detail/Digital-Inkjet-LED-UV-Flatbed-PCB_60772802497.htmlhttps://mimaki.com/application/solution/uv-printing.htmlThere are some sites with DIY experiences using some models of inkjets doable to modify without major issues.

content: I don’t think what you want exists as a commercial product. (Since normal ink is designed for paper, and won’t work on arbitrary substrates, there’s no market for a gantry printer using normal ink. UV cure lacquer, yes, normal ink, no.)What exactly is it you want to print? What kind of masks? And what are the exact failures you’ve been experiencing with normal printers?
