OUCH! 26 is WAY too young to have spine problems. Take care of yourself and work on the physio and recover as much as you can. Hopefully all the way.

In the meantime if you can separate the pages you can use a grapics program to patch them into a single sheet for printing on larger formats. Some care and trial and error will be needed.

Or for plans for stuff that is current with the owners being on this forum ask if you can have the original CAD files.
