Error in 1102 driver

[deichenlaub]

I got the notice that my P1102W laserjet needs a firmware update. I downloaded LJP1100_P1560_P1600_FullSolution.exe. The install went OK. Then I downloaded the firmware file, which also installed OK. Then I re-booted my computer. I got the error message 

An unhandled exception ("System.NullreferenceException") occured in HPLaserJetService.exe [3780].

The Just-In_Time debugger was launched without necessary security permissions. To debug this process, the Just-in-time debugger must be run as an administrator. Would you like to debug this process?

Debugging yielded no useful information so far as I could see. I get the error every time I reboot. The printer seems to be working OK.

Can I revert to an earler driver? Is there a fix?

I am running Windows 7 64-bit Professional.

I am having the same problem under Windows XP Professional SP2 32bit.

This is becoming very frustrating and HP seems not to be doing much so far.

I am also facing this problem ever since updating the firmware. I am running windows 7 64 bit professional. The message pops up whenever I boot up my printer.

I am having the same problem. Mine occurs during the rebooting of the computer. I have the p1102w printer and win 7 professional 32-bit.

Thank you for the reply. I installed the update, and restarted the service and the problem still persist. I have actually sent documentation to HP support with the error message. One of the inconsistencies that I noticed during my talk with HP support is that the display name and the name of the service both has spaces in them. As I understand it, the name of the service should be without spaces. I am not sure if this is contributing to the problem, but you never know with string values and how they may contribute to a NULL exception unless you track down the memory allocation. I hope the problem is dealt with soon. I have the name of the rep that escalated it, but I don't know if I should put that in this message. Either way. Thanks.

Same error with Win 7-32 Ultimate and 1102w when booted. Have had it for months, Does not seem to be an issue with 3 other win 7 boxes on the network??? Also the 1102 will not pause for manual duplex printing--a real pain.

Me too, on Windows 7 64-bit, after installing the latest Full Solution for p1102w.

The problem occurs even when I later try to launch the service manually. I had thought it might be failing at startup because my wireless network connection wasn't yet connected.

Did you install the printer in USB mode or Wireless mode? If you uninstall the printer driver, does this issue persist?

I'm not sure why this occurs, and I cannot reproduce this issue myself.  You may try one of the followings to see if the issue can be avoided:

1. Un-install the driver, and re-install the latest full solution driver on hp.com

2. Use smart install instead of full solution. If you connect USB from 1102w to your PC, you will find a new CD disk appeared in My Computers.  You can enter that disk and run SISetup.exe

Let me know if it works for you.
