Print management issue: cannot remove printer.

@dambron
This is what the fog-client used to manage printers on Windows clients. Maybe try calling those by hand and see if it properly cleans it all up. Start a cmd window as Administrator and run:rundll32.exe printui.dll,PrintUIEntry /dn /n "\\*server*\NCC2100" rundll32.exe printui.dll,PrintUIEntry /gd /n "\\*server*\NCC2100"Huh, well that seems to work just fine, which I guess makes sense. I know that if you add a printer using
RUNDLL32 PRINTUI.DLL,PrintUIEntry /ga /z /n\\computername\printernameThen you can’t remove that printer using the traditional add/remove method in Windows, you must run the /dn /gd commands to remove it.
So it looks like it’s being added properly but the remove command isn’t working for some reason. Very interesting… at least I feel like I understand what’s happening now, if not why! Thanks so much for the assistance.

@dambron I feel I should add - printer management in fog has different modes. ‘Add only’ will only add printers, not remove.
There are two other modes. I don’t remember what they are but - one only manages printers that are in fog, the other only allows fog assigned printers.
So for the managed printer to be managed by fog and removed by fog, the printer must still exists in fog, but be removed from the host via fog.
The other option is much more tougher in my opinion but suites some well. The last is fog manages all printers on a box - if they are not assigned then fog removes it, doesn’t matter if it’s a fog printer or not. Local usb isn’t possible in this setup without creating a printer of the same name in fog and assigning it. I don’t recommend this option.
Looking at the logs, I’d say you are in ‘Add only’ mode.

@Wayne-Workman good point about the “Add only” mode!
@dambron is this still an issue?
-
I am using the “FOG Managed Printers” option for the group/hosts, as I posted previously. There is no “add only” mode that I see. I see an option for FOG to manage only FOG printers (both add and remove), an option for FOG to manage ALL printers (allows it to add and remove Fog and non-FOG managed printers), and an option for it to manage NO printers. I see that the documentation shows the option for “Add-only” and “Add and Remove” but are you sure this is not out of date? I don’t see those options or descriptions in the Print Management menus for any of my hosts and the configuration settings for Print Management don’t contain anything of the sort either.
Also, I’ve tried all the options under that menu, just in case they were incorrectly labeled, and had no different results. The only way for me to remove a printer is by manually running the rundll32.exe print commands on the machine. It seems that the remove commands are not correctly being sent to the host computer via FOG.
PS: I feel like I’m taking crazy pills with all of you talking about add-only mode and patting each other on the back for pointing out something that would be hilariously obvious to me if it were set incorrectly… please let me know if this option is located somewhere I’m unaware of because I do not see it located where the documentation says it should be.

@dambron I am very sorry if it seemed like we were just trying to put you off with this! While being away I got a message from the guy who did all the new client development and he mentioned the “add only” mode just as Wayne did and so I thought I should ask you about it without actually looking into it myself. As I haven’t used the printer management myself I didn’t know that this mode was renamed years ago (Jul 10, 2015). Don’t wanna go back to that so I looked through the current client code again. To me it looks as if the “add only” mode is non existent in the client code anymore.
I’ve looked through the code for hours now but I still haven’t found out why it wouldn’t delete the printers anymore. Maybe it’s time to get a windows client installed and try this out myself…

It’s no problem. I feel bad even making you go through the trouble to look at this, as it’s obviously a lesser used feature. I did find it odd that such a simple thing wasn’t working when every other module/component worked flawlessly. The real reason I would find it useful is that our Helpdesk team manages some business office devices that print checks, tax forms, and sensitive user data. Access to these devices is obviously strictly controlled, but it would be nice if while removing someone’s access centrally we could also cut out their access to peripherals on their network devices.
PS: I love FOG, it’s made my life so much better even in the short period of time I’ve been using it. We’re a small shop and so anything that A.) cuts down on field time and B.) works 99% flawlessly on first install is really awesome for me. I’ll bump that up to 100% if we can figure out what is with the printer removal
-
@dambron Thanks for your message. Don’t worry, I am sure we will figure this out. Just need some more time to become friends with the client code… will keep you posted.

@dambron Making progress here: https://github.com/FOGProject/fog-client/issues/90

@dambron I just updated the github issue linked below. Would you mind testing the new Modules.dll I uploaded. Find the instructions in the issue comment.

I’m posting this just so I don’t forget about it. “Network Printer” and “TCP/IP Port Printer” seem to behave different. fog-client (FOGService) is able to see “TCP/IP Port Printers"?! Need to test this.

@dambron Did you get to try out the modified DLL I provided?
-
@dambron Bumping this…
-
Sorry for the delayed response! We were very swamped with semester start at the middle of August, in addition to just opening a new Center for Science and Health Professionals with tons of new hardware. I didn’t get a chance to test out the new DLL but I was planning on it… until a hurricane hit us and we’ve been closed for over a week and won’t reopen until after Labor Day (I’m located in Houston).
I will at some point test it out and let you know how it goes. Until then I will say that FOG has been an absolute champ and has made my life so much easier for this semester start. I have no clue what I would do without it.
