One of the printers I'm considering for purchase is the HP Designjet 130, but I would like to see some output before making the buying decision. Although I've ordered a sample print from HP, I would like to have one made from my file so as to compare with other printers that I am considering. Does anyone know of a commercial firm using a 130, to whom I could send a file for printing? I've asked HP for this information to no avail.
