Imac (running 10.8) won't recognize wifi printer

My imac (running 10.8) won't recognize one (1) of my two (2) epson artisan 810 printers when I try to add it to my wifi in the "print and scan" utility. The printer that won't connect was previously connected to a PC running Win7. Could Bonjour have something to do with this? Any suggestions on how to correct this would be most appreciated.
thank you, Michael

Repair permissions and restart your computer. Also, check System Preferences/Printe & Fax. Make sure your printer is listed.

My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard (via my MacBookPro), either from the HD or DVD drive. Can't get it to run Hardware Test. Disk Utility says disk OK - files are there. What can I do?

My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard. I erased and re-installed by putting the iMac in Target Disk mode and usin my MacBookPro as the host. But after numerous attempts I still can't get it to boot either from the HD or DVD drive. I just get the white screen after the wheel stops spinning. I can't get it to run Hardware Test - just get the white screen. If I use Disk Utility via my MBP it says the disk appears OK. All the Snow Leopad files appear to have been installed. What can I do?

Perhaps you installed the wrong version OS X onto the iMac, you can't use the disk from another Mac.
clean the disk.
If it's not working then use this method to create a bootable 10.6 USB from the iMac machine specific 10.6 disk or the 10.6.3 retail disk on your other Mac, use it to boot the iMac with.

Computer won't recognize network printer - HP OJ Pro 8600

My computer and printer are both connected to the same wireless network, but my computer won't recognize the printer (using the host name, IP address, or otherwise). It's maddening, because it worked when I first set it up a year ago and just recently stopped - I uninstalled and reinstalled everything. My iPhone can pick up the printer and print wirelessly, but there's an issue when I try to connect my computer using the HP software.

Hi @petersaaron , and welcome to the HP Forums!
I understand you're having issues utilizing your printer from your computer. I would like to the help with that!
I would recommend starting with a power reset. Disconnect the power cord from the printer and the power outlet, then wait 60 seconds. After 60 seconds, plug the printer back in. Ensure you plug the printer directly to a wall outlet. Make sure to bypass any sort of surge protector or power bar.
I would then suggest downloading and running the HP Print and Scan Doctor.
Good luck and please let me know the results of your troubleshooting steps. Thank you for posting on the HP Forums!

Airport Utility cannot find my Airport. It is nearby, no interference, and worked for about 9 months. The Airport still provides wireless internet for the household, though it won't recognize the printer -- plugged in or wireless.

How can I get Airport Utility to find my Airport? It is nearby, no interference, and worked for about 9 months. The Airport still provides wireless internet for the household, though it won't recognize the printer -- plugged in or wireless.

Are you using the latest version (5.5.2) of the AirPort Utility to access the new 802.11n AirPort Extreme Base Station (AEBSn)? Your tagline has it that you are running OS X 10.4.6. You would need at least 10.5.7 to run the utility. I assume that you are running the latest utility on another device ... correct?
When having difficulties accessing the AirPort thru the AirPort Utility, try the following, in order checking accessibility with the utility after each step:
o Check the local connection. If you are trying to access the AirPort wirelessly, make sure that you are connected to its wireless network before running the AirPort Utility to administer it. If you are still unable to access it with the utility, temporarily connect your computer directly using an Ethernet cable to one of the base station's LAN ports.
o Power cycle the base station. Remove the power adapter's plug from the power outlet, and then, wait 15 seconds before plugging it back in.
o Perform a "factory default" reset on the base station.

Help! My computer won't recognize my printer!

I'm a college student, and I have tons of papers and files that I need to print. However, my computer won't recognize my printer. It is working and set up, I plugged it into my roommate's computer (a PC) to see if maybe the USB cable was bad; that wasn't the case.
I've tried to manually add the printer, but I don't have any Printer folder whatsoever in Utilities. If I go into System & Preferences, Printers & Fax, and try to click on the Set Up Printers button, nothing happens. I'm at the end of my ropes. Please help!
Also, the .pdf files for a lecture that I need to print aren't working as well; they worked just fine on my roommate's computer, but when I open them with Preview on my iBook, it is just blank. Does anyone know why this is happening?
Please help me, ASAP! Any advice/anything is greatly appreciated! Thank you!

need more info:
what kind of printer is it?
do have the drivers for it?
do have the printer setup utility?
what version of the OS do you have?
if you have OSX at least, then :
if you can access the utilities folder, you should be able to find the Printer setup Utility. If you do not have that , the n you need to archive and install :
http://docs.info.apple.com/article.html?artnum=107120
if you do have the Printer Setup Utility, then
open that up, it will open a window called " Printer List"
click on " Add"
- that will open a window called Printer Browser
- if the printer is plugged in and powered on, you will see the printer name listed there.
- select it , then click on " add " in the bottom right
- if you do not see any printer listed in the printer browser, then try a different usb port and try again.
- if you are able to add the printer, then try a test print, it should work with a default driver.

My new computer won't recognize my printer (HP4500 Officejet Wireless) in the wireless or wired mode

MY new computer won't recognize my printer in either the connected or wireless mode. When I hit "search for printers" it finds my neighbors wireless printer 100 yards away, and another net, but not mine sitting right beside it.

Hi,
Have you installed its software abd drivers on your computer yet ? Please use the CD which came with the printer. By the way, what is your Officejet 4500 ? It must be G510something.
Regards.

TS1398 iPad won't recognize wifi password after 7.0.2 update. (The password is correct, but iPad says it's incorrect) How do I fix this?

My iPad won't recognize my wifi password after 7.0.2 update. The password IS correct, but I continue to get the message that the password is incorrect. Any ideas how to fix this?

I have the same problem too on my iPad 3. One thing that sometimes works is if you go to the App Store and put your password in there after a few tries it may work.

Welcome to the Apple Community.
No.

I recently downloaded some updates and now my computer won't recognize my printer. How do I fix this?

My computer will not recognize my printer afer downloading some updates.

What updates? What printer? What version of the OS are you running? Information would help.

IMac running 10.8.2 won't recognize my printer!

Suddenly for no reason at all, my computer suddenly does not recognize my Canon MP600. It just stopped working one day and now it's not even listed in the print & scan area. I have unplugged and plugged my Canon back in, tried to find drivers on the Canon website (they say there are none needed for Lion) and I just can't get it working. I would hate to buy a new printer when this one works just fine (usually). Help?

Canon says the driver may be included with the operating system. I'd contact them to let them know you can't get it to work. You can also lookup alternatives on my FAQ*:
http://www.macmaps.com/printersx.html
Lastly, there are these printer updates from Apple:

Unfortuantely you will have to catalog all 7 or 8 pages of search results trying to find the latest version.

IMac 21.5-inch Won't Remember WIFI Networks

Hello. my not-even-1 old iMac 21.5 inch form may 2011 has another problem. It just started happening today. I turned on my iMac and started to use safari, when it said I wasn't connected to the internet. I looked up ath the top-right corner and none of the WiFI bars were filled. I put it back on my router and countinued on. I turned it off a little later, and came back and it did the same thing. I was starting to get concerned, so I reconnected and restated my iMac. It did it again. I read that repairning disc permissions is the best way to fix it. I tried it, but it did not work. Is my iMac broken? Also, it is using a 2.5 GHz Intel Core i5 and is running Mac OS X Version 10.7.4.

My troubleshooting goes:
1) reboot
2) go to activity monitor in utilities and see what processes are running, there may be a surprise there
3) look for the last several things I put on my computer to see if there is a conflict. I once downloaded something that had me going for hours, as the application downloaded shouldn't have messed things up, but it did.
Check that something like the memory isn't loose, go into "about my mac" and make sure everything checks out.
I have had iMacs for over ten years, and one thing I have learned is to trust my computer. All problems were software problems that I caused myself.
Well, if you have Applecare, they can usually spot the problem, though the process takes some time. But I am not an expert, just someone who has had iMacs for a long time.

Slow iMac and Time machine won't recognize iMac hard drive

I have an older iMac (2.16GHz Intel) that is upgraded to OSX10.6.7. Recently it has been running very slow (although it did not seem to correlate with any particular install that I know of). I have looked at the Activity Monitor and cannot find anything that is consuming vast amounts of memory (although I can't say that I really know what I'm looking for exactly, just no high numbers). I did a Safe Boot and it is still really slow there (EXAMPLE of slow is taking several minutes to open a program or taking 27 hours to download my pictures (which only took 13 minutes on my MacBook)). I know my iMac could use more memory (1G), but the slow problem is there even if only running one program. I can't find a particular pattern to it, it just hangs up and then comes back most of the time. It did however start shutting itself down recently. I finally got into disk utility (I've been trying to run disk utility and it usually goes into an eternal spin that I can't even force quit - have to hard boot). So from disk utility I ran verify disk in first aid - it says "the volume Macintosh HD appears to be ok." I"m not sure what else I'm supposed to do in here either. So my first question is Does anyone have any other suggestions for the slowness? Second, in the meantime I'm desperately trying to back up my data on the time machine that I stupidly have never set up as a back up. I can manually put files one at a time over there, but if I try to use it as a time capsule (system preferences, time capsule on) my hard drive does not show up as one of the options???? My external drive and the data that is already on the time capsule show up, but not my iMac hard drive. So my second question is How do I get my time machine to see my hard drive or is there another way to get my files to move over there? I realize I'm in trouble, any help would be greatly appreciated. I've tried to provide as much info as possible. Maybe there is something obvious I'm missing.

My own response, or rather an update: I took the computer up to the Genius Bar - my hard drive is bad. They are going to try to rescue my data. For those of you reading this with a similar problem, make an appointment and go to the Apple Store if you can. Mike, my personal "genius" for this encounter, said that stressing the machine when the hard drive is going bad just risks damaging it more. If you potentially have a hardware issue, take it and let them determine what is wrong. They have tools and diagnostics most of us wouldn't know how to use if we read about them here - and they have ways of retrieving data (I hope) that most of us do not have. Please note that disk utility said my hard drive was ok, but the diagnostics they did showed that in fact my hard drive was much less than ok, but it was still "mounting" hence the disk utility reporting it was ok. It is over an hour drive for me to get to the Apple store, and I only wish I had gone sooner.

Airport Express won't recognize TSC printer

We are having a really weird issue with a new 802.11n Airport Express. It refuses to recognize a specific USB printer attached to it (TSC TTP-245c label printer, to be precise). By "refuses to recognize" I mean the printer does not show up in the Printers dialog within the Airport Utility (5.6 in this case... don't even get me started on 6.0, which doesn't even HAVE a printer dialog anymore) and attempting to send print jobs to it fail.
Anyway, the really bizarre thing is that the Airport Express DOES see other USB printers we connect to it, and the TSC printer DOES work fine on other USB print servers, or from a notebook PC via USB, etc... even an OLD g-only Airport Express can see the TSC printer just fine. It's ONLY the specific combination of a NEW Airport Express and the TSC-245C printer that doesn't work.
I'm sure I'll get replies asking me to update a driver, update firmware, etc. So let me save you the trouble... this has absolutely nothing to do with drivers as the print server (Airport Express) itself cannot see the physical printer attached to itself, and the Airport is already running 7.6.1 (though I did try and revert back to 7.5 to see if it made any difference, and it did not). I also verified that the TSC printer is running the latest firmware available for it.
So what do you do when you have two devices that are working fine independently with OTHER devices, but won't work with EACH OTHER? Is there any way to get this information to Apple so they can investigate why their new device is having trouble with this one particular printer model? I've already started the process of telling TSC that they need to obtain a new Airport Express to see if they can figure out what's wrong, but it could very well be a problem on Apple's side... after all, their OLD Airport works against this printer just fine.
All that said, I'm not expecting to get any magical fix from these forums... I'm mainly trying to find out how this can get "run up the flagpole" at Apple so they can perhaps investigate. Is anyone aware of similar problems with OTHER brands of printers? Again, the symptom is simple: Connect a USB printer to the new AirPort Express and it just isn't seen by the Airport.
Any advice appreciated!

I don't think all printers will work.
Have you read this Apple article?
http://support.apple.com/kb/TS1253
Still not working?
If your printer still doesn't work with AirPort Base Station or Time Capsule printer sharing but does work when directly connected to your Mac, contact the printer manufacturer for additional information.
As the article states above, you would have to contact the printer manufacturer.

My macbook pro won't recognize network printer

Macbook pro is late 2011 running OSX 10.7.5 - Lion, connected wirelessly to home network with airport express.
Have an HP deskjet connected with a cable to a MacMini mid 2011 - Yosemite.
macbook always has problems printing to this printer on home network. "printer not found" or "printer not connected"
Normally I turn off the printer and back on and it will print. Now I just get message "printer not connected"
I deleted the printer and tried to add it back and it will not find the printer.
Is it possible to reset the airport express? Will it benefit me? Is the issue that yosemite and lion do not get along?
I really would like to be able to print from the macbook without having to unplug printer and plug it directly to the macbook.
Frustrating to say the least!!!

I had almost the same thing happen the other day - kept getting a message that my printer was not connected. I went to the printer setup on the printer's panel and the IP address was correct, everything looked as if it should be working. So I just reset my router - figuring that would fix the problem. No go. What I finally ended up doing was resetting my router to factory settings and setting it up anew.
And that's what worked for me.
