Print.print_printer does not appear in about:config

Everytime I try to print from Firefox the printer hangs up. I read your HELP on resetting the print.print_printer in about:config. When I went to about:config there was no such entry. How do I add an entry and set it to the default settings?

I also find there is no entry in the list for print.print_printer and that there are probably 60 configuration entries for my printer. When I try to print from FireFox the printer acts like it is receiving data, and then feeds a sheet of paper, but prints nothing at all. Printing of the same output from IE-8 works fine.
My problem with the printer showed up about 2 days ago. To my knowledge, nobody changed any printer settings.

The Search field "print.print_printer" does not show in about:config. I cannot reset

When I print from a selection from the web, half of the 1st line is missing. I have 2 printers: HP Officejet 5510 & HP Photosmart 7520. When I print from 5510, the page will also show the "address" at the top & the date/time & page number at the bottom. None of this happened until today.
I have Windows 8
When I print with the 7520, the address & the bottom part are barely printed.
I reset the top margin to 1" from .5 that I had done yesterday when I doing some print jobs, but it did not change the parts that got cut off.
I found a printer problem page on your site & the subject I listed is not available so I can attempt to reset Firefox.
Thanks for your help

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try these free programs to scan for malware, which work with your existing antivirus software:

Epson r800 prints, but does not appear in Printer List: can't use Utilities

My Epson r800 prints, but does not appear in Printer List. It is connected via USB to the iMac. A Brother LH-2070N is connected via AirPort Extreme. I need to use Utilities to clean the head of cartridge, check levels, etc.. Is there a way to fix this problem?
iMac Mac OS X (10.4.9)

For your Epson try this:
Hard Drive, Library, Printers (folder), Epson folder,
Inkjetprinter folder, Utilities folder and here you
will find Epson Printer Utility2. Click on it and it
should work.
Note. Epson utilities will not work unless the
Printer is directly connected to the computer.
Had the same issue with my 2200 photo and the above
worked.
Tried again after reinstalling the drivers. There is no separate Inkjet Folder, but the Printer Utility is within the Epson folder. Unfortunately, the r800 still does not appear in the Printer List, hence no utility.

First of all, update Firefox to 3.6.17 via Help | Check For Updates.
There was a security breach at Comodo which is an SSL certificate provider recently whereby a number of fraudulent certificates were inadvertently issued. These allow a hacker to impersonate any site including online banking and the Firefox version you're running at the moment will not warn you that the site is a fake. The fraudulent certificates were blacklisted in v3.6.17 and beyond.
To uninstall the Yahoo Toolbar, go to Tools | Add-ons | Extensions. You should find it in there.
To revert to Google as your preferred search engine, please do the following.
* In the location bar, type '''about:config''' and hit Enter.
* In the filter at the top, type: '''keyword.URL'''
* Double click it and remove whatever's in there and replace it with http://www.google.com/search?q=
The URL to add in "keyword.URL" becomes a link in this post, so right click it and choose "Copy Link Location" to copy it to the Windows clipboard. Then hit CTRL+V to paste it. Saves you having to type the whole thing.
'''To reset your home page, do the following'''.
* Go to the site you want to set as your homepage.
* Go to '''Tools '''| '''Options '''| '''General'''
* Make sure it says "''Show My Homepage''" in the first dropdown menu.
* Click the button called "'''Use Current Pages'''" to set the homepage to the one you have on the screen.
After you complete the above steps, install this add-on to prevent another search engine from modifying your preferences: https://addons.mozilla.org/en-US/firefox/addon/browserprotect/
Additonal security risks on your system are the version of Flash you have installed at the moment. See http://www.adobe.com/support/security/bulletins/apsb11-12.html

Hp officejet 4500 prints but does not appear in devices and printers in Windows 7

My wireless hp officejet 4500g prints fine wirelessly but it does not appear in Control Panel Devices and Printers in Windows 7. Do I have to go through all that uninstall and reinstall. I've used Window 7 Troubleshooting Printer check and all was fine.. Thanks for any help

Hi,
If the printer successfully print, it do exists within Devices and Printers..
Windows 7 may merge several devices into a single icon, right clicking a merged icon will let you then choose the specific device as you may see in the following screenshot as a sample:
Check any existing printer icon and locate the one your printer combined with..
If none of the printers does not list the 4500 printer make sure to right click the Computer icon within the Devices category, I notiice the printer sometimes merged within the computer as well, then you will see any printer options (e.g. Printer Properties, Printing Preferences within the computer menu.
Hope that may help,

New Downloaded/Installed Cannon PPD Print Driver does not appear in driver list

I have downloaded and installed every new driver, 5 times, including he PPD driver for the Canon imagerunner 5570 printer, however when I add the printer the PPD driver does not appear in the list of drivers. the printer is on a wireless network and I was able to print before updating. I had not set up Time Machine until today so I can't go back, or can I. I am a new Mac owner so please be gentle.
Thanks

The PPD installer will copy files to HD > Library > Printers > PPDs > Contents > Resources > en.lproj and the file names will be "cnxxxx.pdd". Can you first check that you have all the files installed.
If you do have the files then you can add the printer using IP > LPD for the protocol. Note that the iR5570 does not support Bonjour so it won't appear in the Default view of Add Printer as Zlig suggested. You then enter the IP address of the iR5570, leave the queue name blank, change the name to something meaningful and then search for the ir5570 in the Print Using menu.
If there are no Canon iR models listed in the Printer List (typing iR in the Search field will determine this) then you should try resetting the printing system as follows.
1. Open System Preferences > Print & Fax
2. Move the mouse over the Printers list.
3. Hold down the Control key and then click the mouse
4. Click on the 'Reset printing system' pop-up
5. Close Print & Fax and restart your Mac
This will remove all the printer queues from Print & Fax but will not remove the printer drivers installed on the Mac. So you can try adding your print queue to the iR5570 again using the process above.

The setting print.print_printer is missing from my about:config in OS-X 10.8.4

Hi,
I can't print in Firefox. I started the troubleshooting process, but when it gets to resetting the print.print_printer option I can't because it doesn't exist in my about:config.

Printer Pool does not appear in Available Printer list

I run a school lab with 35 iMacs in it. We have 2 network printers. I am trying to set up a print queue on our XServe to pool the printers so that jobs will go to whichever one is free/not out of paper/etc. I have successfully set up queues for the individual printers and I have created a printer pool, which I set as the default queue.
The problem is that when I look in the students' available printer list, all I see are the queues for the individual printers and not the pool. How do I make the pool appear so that I can set it as the default printer for the students?
Thanks in advance.
Nancy

Apparently, that is how it is designed.

Printer dialog box does not appear in Photoshop CS.5

I use Photoshop CS.5.1 with a Macbook 2013 using version 10.9.5. The printer works perfectly with all other applications but in Photoshop no printer dialog box comes up and the print job does not appear in the printers queue. Anyone the same issues?

First, try nuking (deleting them and letting the application create new ones) your Photoshop preferences:
To re-create the preferences files for Photoshop, start the application while holding down Ctrl+Alt+Shift (Windows) or Command+Option+Shift (Mac OS). Then, click Yes to the message, "Delete the Adobe Photoshop Settings file?"
Note: If this process doesn't work for you while you're using a wireless (Bluetooth) keyboard, attach a wired keyboard and retry.
Important: If you re-create the preferences by deleting the Adobe Photoshop CS6 Settings file, make sure that you only delete that file. If you delete the entire settings folder, you also delete any unsaved actions or presets.
Reinstalling Photoshop does not remove the preferences file. Before reinstalling Photoshop, re-create your preferences.
NEW Video! Julieanne Kost created a video that takes you through two ways of resetting your Photoshop preferences. The manual preference file removal method is between 0:00 - 5:05. The keyboard shortcut method is between 5:05 - 8:18. The video is located here.
Mac OS
Important: Apple made the user library folder hidden by default with the release of Mac OS X 10.7. If you require access to files in the hidden library folder to perform Adobe-related troubleshooting, see How to access hidden user library files.

Printer driver for lexmark x6570 does not appear in printer setup utility

Hi
I have just bought a lexmark x6570 wireless printer and have installed the driver on my powerbook, set up the printer (using a usb lead as instructed) but am unable to print anything as the printer driver does not appear in the printer setup utility. I have even tried to move the folder that was created on the desktop to the printer folder in the library folder but still no joy.
Someone help me please!

Installed HP Officejet 4100 All-in-one does not appear in Control Panel printer selection window.

My HP Officejet 4100 Series 'All-in One' DOES NOT APPEAR in the Control Panel window even after several re-installs. The diagnostics indicate that the 4100 is not connected and dos NOT point to any path for a solution.
Attempts to download a current Driver, ( or re-load the 4100 "software" ), WILL NOT work because the 'help' page states the driver already comes with the 4100 software and therefore does not provide for any download update, (driver or software) for the 4100 printer.
I have reinstalled from the original Disk for the 4100 and also attemped install with Windows Update requested driver. Nothing works.

Hi there @Past77
Welcome to the forums
I read your message about your Officejet 4100 not showing that it's connected, and that you have attempted to run the Windows Update to see if that would help get the printer working again. You are correct that this model does not have a downloadable driver for Windows Vista, so your best bet would be to try running the Print and Scan Doctor tool, to see if it can kick the printer into gear and have it functioning again.
If the tool does not work, I would then recommend looking in to a printer upgrade. Consider giving us a call to see what your options are with HP.

LR 4 - image does not appear in Preview and will not print`

The selected image appears on the main/center panel but not in the preview screen. Printing results in a white sheet of paper with no image at all. The image has been updated to LR 4 - but made no difference. I've served help and the forums (where i saw mention of similar problems, but no comments or guidance on the problem). What am I doing wrong?

The problem began with the installation of LR4. I print directly from LR4 to my HPZ3100. I routinely select "print preview" in the print dialogue box. Now the first print I see the preview and then it prints. If I select a second print job and use the "print preview" the print preview screen comes up blank and never loads. If I try to delete the print job, it just never responds (resolves) so I have to turn off the computer and the printer and restart to clear the print job. if I don't use the print preview, it prints just fine (except that I'm not able to check what's about to be printed). Thanks for any thoughts you have on this.

Bill, if this is only happening some of the time, then we are probably looking at a resource issue. Any pattern in when things won't print? e.g. Certain file type won't but others will? Or is it more of a timing/order thing? e.g. First file prints fine, second does not? VStromee, do no files print for you? Or is it like Bill and sometimes the print and other times they do not? Did you install any new software recently or have any updates to the OS or any application that has printing capabilities?

and the other being the issue where IOS can return the prompt before it's done unpacking the files
Ok, now what EXACTLY is the appliance and IOS version? The only time I know of this bug is the Metro Ethernet (ME) switches and when the current appliance is upgraded FROM an IOS version 15.2(1)S.
But there is a "workaround" which Cisco doesn't want to publish (don't ask me why not): Use "archive tar /x" and, optionally, delete the old IOS sub-directory.
Personally, I wouldn't recommend anyone using the "copy the BIN file" method unless you know what you are doing or you've put extra measures in place. The "archive /x tar" and/or "archive download-sw" was developed so that it could be automated and the operator can see the result at the end. The "copy the BIN file" method doesn't give anyone a result whether or not the file was copied or not or was the file copied completely.
Regularly, I would upgrade our switches (2960/2960S, ME-3800X, 3560E/3560CG, 3750X) fleet using the "archive download-sw" method and I don't use scripts. I just copy-and-paste the command. So far, since 2009, I've "lost" only 6 switches when I upgraded the switch to upgrade the wrong file (another IOS bug on it's own) and I had to physically show up and upgrade using ROMmon. Every time I would upgrade, about 900 switches (some in a stack), it would take me about 4 days. Even though I work with three guys who's very good at almost any scripting but we've come to a unanimous conclusion NOT to use scripting.
Moving on, if "copy the BIN file" is still a preferred choice, I would like to know how do you go about verifying the file was copied completely? Whenever I resort to the "copy the BIN file", I ensure the file copied is complete by verifying the MD5 hash value against the MD5 hash value found in the Cisco website. Trust me, adding this additional "layer" of security saved me doing ROMmon upgrade so many times.
