I bought this scanner because the old Canon scanner Lide30 no longer under Win7, 8 and 8.1 may be used, there is no driver. The was scrapped, even though he is technically still in top order. The new Lide120 is faster and quieter. Pleasant is still that he still does not require the hassle of power adapter. This new scanner is now running under Win7 and 8 / 8.1 without problems under WinXP the properly installed HP7350 is not recognized, a very weak freestyle manufacturer! The menus of the supplied programs are quite cluttered and confusing. Want to save the scans do not understand the software. To scan of image details one must always only durchhangeln to "ScanGear". That's a fumble in the menus. Overall, not a very nice solution. The next time is probably Canon not back into the house. The only thing is, however, always impressive is the product quality. There has never been failures with Canon products.
