Im looking at getting the HP 8450 printer. I have managed to find two HP part numbers for the printer Q3388A and Q3388B. If you search for these part numbers on the HP website you appear to end up at the same product. Going by the HP site it is the same printer. Anyway I have found a retailer that appears to be selling both of the printers by each part code, there is almost £60 differance between the two! (£117.49 vs £178.33) inc VAT ex delivery. Obviousy I am looking at the cheaper of the two !! Does anyone know for sure if at all there is any difference between the two models?
