scanjet 4500/­5550 series alternative TWAIN drivers for HP Scanjet 5550c This software provides TWAIN drivers as an alternative to the hp photo and imaging software scanning software that comes with the hp scanjet 4500/­5550 series of scanners.­ These TWAIN drivers are an efficient way to gain access to TWAIN functionality.­ Many document management systems do not require all of the extended features included in the hp photo & imaging software.­ Without these alternative TWAIN drivers,­ the entire hp photo & imaging software package must be installed in order to have access to a TWAIN driver.­ Moreover,­ alternative TWAIN drivers offer users a streamlined workflow for heavy document management and require less hard drive space for installation than hp photo and imaging scanning software.­ Before installing and using the alternative TWAIN drivers,­ users should be aware that no user interface is supplied with the TWAIN drivers.­ In most cases the software used with these TWAIN drivers will control the scanning process and the results will be completely satisfactory.­ However,­ it should be noted that some applications,­ like ScanSoft's PaperPort,­ rely heavily on the host scanner's TWAIN user interface to change settings such as resolution,­ color level and page size.­ Because of the lack of a user interface with these alternative TWAIN drivers,­ and thus no opportunity (except in some applications) to change the scan settings,­ this software will not be ideal for all customers.­ NOTE: this version of the file is the same as the previous version (originally posted 4/­7/­04) except for the installer.­ The install did not load the digitally signed drivers correctly which caused a "Digital Signature not found" error.­ That problem has been fixed in this version.­ Compatible devices: C9919A
