Title: USB Parallel Port adapter - different maker same problems
Product review: Living in Switzerland, I bought a like device from a local multiple store. It would not work with my HP DJ 720C but did work with my Canon BJC 250C. In addition, from this same store I bought a 4 to 1 USB switch (to connect up to 4 PC's to one printer). This box worked with the motherboard USB's but happily blew the O/P driver circuits of my dual port plug in adapter - PCI to USB - card. It's clear the market is supplying shoddy USB products - anyone know of a USB User Group? we need to pool our data and get to manufacturers and suppliers. (I also have many years experience as an electronics engineer).
Would you say this review depicts the product in a flattering or unflattering light?
