Many things about reporting from Coda are possible; I assume by “this” you mean exactly the what the title says - Saving a view as a PDF.
I know my accounting department closes the left nav tab and uses Chrome to File | Print to PDF with great success. Using landscape output and ensuring the browser window is not excessively wide, the tabular reports based on views and Cross-Doc tables are very clean looking.
I also do a lot of stuff like this using Google Apps Script integration.
