.JS Logon script – Printers randomly not connecting

mjgreen · April 29, 2009

Hi all,

I have just started a new job as an IT Tech in a school. We use a javascript (.js) logon script which connects to a set of network printers depending on the location of the PC.

In the last couple of days, things has been playing up. Randomly printers will not connect. Sometimes all the printers and sometimes only 1 or 2 of the printers and sometimes none of the printers.

I don’t think that it is a problem with the script, as it has been working fine previously. Also the fact that sometimes all the printers are connected fine and other times not suggests to me that it is more likely to be some kind of maximum connection problem or something.

Anyway, i have been looking round the web for the last day or so without much luck.....has anyone got any ideas for things I can try?

The only change recently is that I updated the driver for one of the printers on the server.

Many thanks

Hi, am i right in saying that some of the PC's are/should be connecting to more than one network printer when they logon???? or are you saying that if I log on to the network at one part of the school (maths room) I want to see only the maths room network printer?

is it possible to have a look at you script? also I have had this before and some times putting a shortcut of the script on the desktops so that they can run if it does not map properly is a workaround until its fixed.

yeah must admit, I have been thinking about the a shortcut as a work around but its not ideal if we can avoid it. Also (as I just found out) sometimes you need to run the script up to 10 times to get the printer to appear....I am sure this must be some kind of time out or something.

In regards to your first question, the printers that are connected should depend on the location in the school. For example:

A Pc in the Library should have access to the 'Library Laser' and the 'Library Colour Laser':

On the PC in Library we add the Envoronmental Variable 'LOCATION' with the value 'LIB'

The script then looks for this 'LIB' and assigns it the appropriate printers.

However, only the 'Library laser' was connected and not the 'Library Colour Laser'. Several manual script runs later, both printers will finally appear.

I dont think it is a problem with the script as it has always run fine in the past, and it does work manually eventually. Also the problem is completely random in terms of location in the school (e.g. The Library might be fine for a week now, and then randomly the problem will start again)

OK, what you could try is deleting the variables and then re-creating them again with the existing name (LIB) or create a new variable name on the PC and change the script so it looks for the new variable, is there any way that you can use the force command in the JS script to tell the PC to connect to the desired printer???

1 more thing is to try and install con2print. its exactly what you need to do and its what i use at all of the schools that i look after.

here is the download link........ its all basic scripting, you just unzip and paste the con2print.exe into your Netlogon folder and create a new .bat file calling con2print. any probs message me.

Hope this might help.

Thanks for your help.

I don't really want to start looking down the route of switching the script to a different method at the moment (wouldnt be up to me anyway!), but I will certianly try your other ideas.

Just seems strange as the script appears to run perfectly fine on all machines for 95% of the time, they just randomly seem to have these blipps(its only started happening in the last few weeks) so im not sure changing/refreshing the 'Location' variable will help....especially due to the fact that most of the time it goes wrong, it will still connect to 1 of the printers which you would not expect if there was a problem with the 'Location' variable.

True, it does seem a little weird, Sorry I cant be any more help to you, i have experienced this in the past and sometimes just re-creating the var normally works.. if you do manage to solve let me know...

thanks

cool, will give it a go this afternoon....it always gives you that bit more confidence when someone says that they have experienced it themselves!

thanks again, will let you know how I get on

We might finally have a breakthrough!

...and it looks like nothing at all related to everything I was guffing on about!

Looks like when I updated an HP driver on the print server recently, it also installed something called hpboid.exe, which is some kind of HP status server. There was about 10 instances of it running in processes....

just a quick google search for hpboid.exe suggests loads of issues with it causing delays etc. We have stopped the service's related, deleted the running processes and touch wood.....so far so good!

Time will tell I guess.

Thanks again for your help

cool, thats a bit weird, was the driver the basic driver from the HP website? or was the full package? its sounds like the full package and with that it has installed an additional piece of software. im glad that has hopefully fixed it:)

I thought it was just the basic drivers, could be wrong though...it was a couple of weeks ago now :-/
