Appendix A: Job Status and Alerts
HP Color LaserJet 4550 Software Technical Reference 174
Steps to remove support for a specific driver
1. Open a command prompt window.
2. Change directories so that the current directory is the windows\system directory (for win9x
systems it will typically be windows\system, for NT/2K machines it will be winnt\system32).
3. Make sure Job Status and Alerts is shutdown, if it is not right click on the Job Status and
Alerts tray icon and choose exit.
4. Type the command: hpbdrvhk –r “printername.”
5. Repeat step 4 for each printer name that is to be removed.
6. Type the command: hpstatus.
7. Job Status and Alerts will no longer support any printer that refers to the same driver model
name.
Driver support matrix
The status component determines which printer drivers it supports by consulting a file called the
Driver Support Matrix (DSM) named HPJob Status and AlertsDRV.MTX. This DSM file is nothing
more than an INI file that contains entries of driver model names that it specifically supports, or
specifically does not support.
DSM File Format
The format of the DSM file looks like:
[Driver Model Name]
supported=[0|1]
Each driver model name that status supports will have an entry in this file. For example
the 8150 PS driver would have an entry in the DSM file that looks like:
[HP LaserJet 8150 Series PS]
supported=1
The DSM can also have entries that specifically prohibit known drivers that status will not
support:
[Driver Model Name, NotSupported]
driverFileName,x.y.z=1
This type of entry is used by status to exclude support for a specific driver model name,
using a specific driver file and version. For example, the 8500 PCL drivers for 9x and NT
are not supported because the printer drivers are not written in a standard way that status
proxy drivers can hook the OS functions they call. Disabling support for these types of
drivers is accomplished by having the following entries in the DSM:
[HP CLJ 8500 - PCL,NotSupported]
HPCPCLA.DRV,1.0.0090=1
;; windows 9x pcl driver is not supported
[HP CLJ 8500 - PCL,NotSupported]
HPCPCLA.DLL,1.0.0090=1
;; windows NT4 Kernel Mode driver is not supported
