All the document in only one long and continuous page

2673cm is 26.73m. The TeXBook says

danger TeX will not deal with dimensions whose absolute value is 2^{30} sp or more. In other words, the maximum legal dimension is slightly less than 16384pt. This is a distance of about 18.892 feet (5.7583 meters), so it won't cramp your style.

This previous answer is not exactly true. You can create a \vbox with arbirtary size, so you can (for example) do

\setbo0=\vbox{... whole document ...} 

The problem is, what to do with it. You can do \shipout\box0 to print it, but the PDF page dimensions are not properly set because we need to set such page dimensions by TeX dimen registers and the mentioned limit about 5.7 meters is here. But if an interpreter of your document can handle with page dimensios a it is able to change them, then you have whole document in one column with 26 meters hight. Maybe, you have a special device which is able to print it.

If you use dvi output then \shiput\box0 (from previous example) cerates correct output because dvi format does not care about page dimensions. These dimensions are set by the dvi driver. Maybe, you have a dvi driver which is able to print your document on skyscrapers. And if not, you can create such dvi driver.

Another possibility is to create normal (small) document but to use a \mag TeX primitive register. It puts to the output the scaling factor of whole document as a message for PDF interpreters or dvi drivers. So, you can prepare a small document, test it on your personal printer and then you can put \mag with big scaling factor. You can print the same document on airships.
