You can try laser toner transfer. I have not done anything as fine as TQFP but you can see my double sided board project last summer using toner transfer and HCl/H2O2 etch at http://wb8nbs.wordpress.com/. I have a 12 year old Lexmark 4039 10+ laser printer. The traces came out clean enough that I think TQFP is possible.
