Very different from a CanoScan 110, the same simplicity, this HP ScanJet 5590p requires concentration, luck and some aspirin if you want a successful installation. I almost return it to Amazon so it is horrifying.
The carton also contained unidentified contraptions that remained. HP does not consider it useful to include a booklet giving the ID of its objects, or giving the user manual to integrate. Bad, after all, you did good garbage.
