I have several Macs printing to an HP LaserJet 4000TN on my LAN. All but one work fine. Even the Windows machine works. The bad actor is a new MacBook Pro.

When I try to set the printer up (using the HP JetDirect IP connection), for some reason it can't figure out which driver to use—I have to manually select it. And very often it refuses to print, saying that it can't connect to the printer. Power cycling the printer fixes it temporarily (printer is set in Energy Saver mode but wakes up fine for other machines).

All my other Macs (all using latest Snow Leopard) work fine. What's the problem?

13" Macbook Pro (mid-2010), Mac OS X (10.6.4)

    AppleTalk no longer exists in Snow Leopard, which is how it communicated with that printer. You'll have to add it via an IP address. Using the buttons on the top of the printer, kick out a Configuration Page. The IP address assigned to the printer by your router will be on that sheet.

    To print a configuration page:
    1 Press Menu until INFORMATION MENU appears.
    2 Press Item until PRINT CONFIGURATION appears.
    3 Press Select to print the configuration page.

    Now add the printer as IP. Choose HP JetDirect as the connection. Enter the IP address as shown on the Configuration Page. Put a logical name in the name field, which would be the obvious "HP 4000TN".

    Thanks, but all my Macs use IP to address the printer (via the JetDirect option). I have manually assigned an IP address to the printer and when I input it into the MBPro's printer setup, it apparently can see that there's a printer there but can't tell what kind it is. None of my other Macs have this problem, and they're all running 10.6.4.

    Is the PPD missing from the /Library/Printers/PPDs/Contents/Resources/ folder (may be in the en.lproj subfolder)? If so, copy it over from one of the other Snow Leopard drives and then select it as the PPD in print setup.
  • G Robert Lewis Level 2 (225 points)
    No, the PPD is there. I'm re-downloading the latest package of HP Printer Drivers from just in case.

    The perplexing thing (or one of them, anyway) is why power-cycling the printer will clear the hang, but it's only needed when this computer is trying to print.

    Interesting: now my MacBook Pro is having problems printing to this printer. If I open up the queue, it says "Connecting to printer...Unable to connect to printer. Will retry in 30 seconds", and it just sits there.

    Interestingly, this same queue window also says "Toner low". The obvious question: if it can't connect to the printer, how on earth does it know that the toner is low?

    Second question: could the "toner low" alert be enough to hold up the printing operation? I know the toner's low: I'm getting the last pages out of it by periodically removing the cartridge and giving it a shake. Prints fine--when it prints.

    i'm assuming you've already done this.

    Have you compared the other mac's settings to the mac that's giving you problems?

    If I open up the queue, it says "Connecting to printer...Unable to connect to printer. Will retry in 30 seconds", and it just sits there.

    That's what my Xerox 6280DN does under Snow Leopard if I add it the normal way in the printer setup. This even with SL drivers from Xerox. I had to print out a configuration page to get its IP address and add it as a Line Printer under the IP heading to get it to work properly.

    I'm having the same "low toner" issue which is preventing my MBP from printing. I replaced the toner cartridge last night hoping to resolve the issue, but its still there. Is there anyway to override or bypass this "feature"? I'd happy to have my printer tell me when the toner is low than my Mac.

    I have the exact same issue - I can print to my wireless HP photosmart printer from my Mac Mini, but my macbook gets the cannot connect to printer message. I also have the low toner message - but it sounds like someone has proven replacing the cartridges does not fix it.

    This is clearly due to a recent update as this computer has been able to print to that printer for a long time.

    I'm having the same issue with my Mac Book pro and HP Laserjet printer.

    Has anyone had any luck with this?
  • Charles Dyer Level 4 (2,620 points)
    Which HP LaserJet printer? Some are no longer supported. Others will work if you go about it the correct way. Others work out of the box. You need to say which one you have so that we can know which category yours falls in.

    similar problem: Brother MFC9700 networked thru a shared multimedia drive. I went thru a set up on the new MacBook Pro as directed by the drive manufacturer and now have a message that "Printing paused". Window computers print easily, no issues.
  • Charles Dyer Level 4 (2,620 points)
    I take it that you've got the MFD connected by USB, right? What kind of 'multimedia drive' is it connected to? How does that device see the network? What happens if you connect the Brother directly to a computer? Does that model have an Ethernet port? If not, can you attach an USB-to-Ethernet print server to the USB port?

    I'd say that the odds are excellent that the problem is with the 'multimedia drive', which might have Windows but not Mac drivers for its USB printer connection subsystem. An Apple device, such as a Time Capsule or an AirPort Extreme, ships with the correct settings to share printers and MFDs to both Macs and WinBoxes, but some other devices don't. Which one are you using?

    Error Message: "Unable to Connect to Printer, will try again in 30 seconds...

    I have the same problem. It just started a few days ago. Prior to that, it was printing fine. I recently did an Apple Software update, so I'm guessing that's where the problem originated from.

    I have a Brother Multifunction that's setup on my WLAN.
    I got the message after attempting to:
    Factory reset the printer and setting up WLAN again
    Uninstalling all Brother Printer and Scanner Drivers and Reinstalling
    Switching to WiredLAN to print

    Same Error Message Each Time

    Two days ago, I also installed a new print cartridge. When I saw the levels a day later, it looked like it was half used - No Way!

    There is obviously a miscommunication between ink/toner level and new cartridges and the Apple Drivers for WLAN.

    To my knowledge, there is no fix at this time and Apple needs to resolve this high priority.
    What I don't get is why won't the wired config for the printer work either?

    Last fix attempt: Take out all cartridges and reinstall. No Juice!

    My Findings: The Latest Apple Software Update will screw up the communication between your Mac and print drivers.

    Solution: It's all On Apple to fix this ASAP!
