HP Color LaserJet 4550 Software Technical Reference 221
The HP 4550 does not have a device CMYK mode but will work well in the Vivid RGB mode with either the PS or
PCL driver provided the application supports RGB ICC profiles.
3.3 ENABLING CMS SUPPORT IN MACINTOSH OS

3.4 ENABLING CMS SUPPORT IN WINDOWS OS
The HP4550R.icm or HP4550C.icm ICC profiles can be installed at the system level using ICM-2 built into the
Windows 98 and 2000 operating systems. Windows NT 4.0 does not have ICM, and ICM-1 on Windows 95 is not
supported. The HP4550C.icm CMYK profile can only be used with the PS driver while the HP4550R.icm sRGB
profile can be used with any of the HP4550 drivers.
ICM is not recommended for use with the HP Color LaserJet 4550. The default RGB path is sRGB which is
compatible with the default settings of ICM and all color data processed through the Windows operating systems.
The default ICM profile is "sRGB Color Space Profile.icm" and works very well with HP printers. If there is a need
to manually enable ICM, it can be done from the Printer Properties dialog, or by right-selecting on the profile as
described below.
ICM is enabled by associating an ICC profile with the printer. Microsoft Office and other applications including
Microsoft Word, Microsoft PowerPoint and Microsoft Publisher will process printer colors through the associated
ICC profile when a document is printed. A profile can be associated with the printer in two different ways:
Enabling ICM by right selecting on the profile:
Copy the ICC profile to the appropriate directory for the OS.
• Win 98 \<windows>\system\color
• Win 2000 \<windows>\system32\spool\drivers\color
Hold the mouse pointer over the profile name, HP4550r.icm (recommended for PS and PCL) or HP4550c.icm (PS
only), and select the right mouse button.
Select "Install Profile." Right select on the profile again and select "Associate". A dialog box opens to select the
devices this profile is associated with. Select "Add…" and choose the correct HP Color LaserJet 4550 printer.
Enabling ICM from the Printer Properties dialog box:
A second way to view, install or change the ICC profile associated with a printer is to open the printer properties
dialog box. Under the "Color Management" tab any profiles associated with the printer is shown. Select Add…
and choose the file HP4550r.icm. Select Manual while this filename is selected to make this the default profile for
the printer.
The HP4550 PS driver has additional control over ICM when printing under the Advanced Options of the Printer
dialog . The ICM Method: ICM Handled by Host System and ICM Intent: Pictures options are recommended.
