========================================================== README file for HP DeskJet 1600C NT4 Printer Driver May 1998 ========================================================== This document contains important information about what you must check before installing the HP DeskJet 1600C NT4 printer driver software. Before you install the printer driver, be sure to read this document and fully understand its contents. ----------------------------------------------------------- Introduction ----------------------------------------------------------- Welcome to the HP DeskJet 1600C NT4 printer driver. The HP DeskJet 1600C NT4 printer driver is compatible with Microsoft Windows NT 4.0 (hereon referred to as Windows NT 4.0). ----------------------------------------------------------- Application Specific Notes ----------------------------------------------------------- Photoshop 4.0 - Output looks mottled or too contrasted In the Print dialog, change Print as CMYK to Print as RGB. Microsoft Word - Printing Envelopes When printing envelopes out of MS Word, Word checks a list of known printers to decide how to print the address information on the envelopes. If the printer is unknown, it uses a default feed path. Since the driver name is HP DeskJet 1600C NT4, Word does not recognize it and assigns an incorrect feed path to the envelope. This results in the return address being cut off. To correct this, do the following: on the envelopes and labels dialog, click on the envelope icon under feed. This will bring up the printing options. Choose the feed method on the far right, then clear Clockwise Rotation and select Face Up under Feed Method. This will allow the envelopes to be printed properly when they are fed into the printer face up and stamp side first. ----------------------------------------------------------- Notes for Uninstallation ----------------------------------------------------------- It is highly recommended that old versions of the HP DeskJet 1600C driver be removed from Windows NT 4.0 before installing this new version.
