Sir/Madam

The latest HP printer driver for devices listed below are built into Mac OS X 10.6. You do not need to download or reinstall any HP software for full printing functionality.
HP LaserJet print drivers are included in Apple's Mac OS X 10.6 Snow Leopard DVD and also available via Apple Software Updates.

Snow Leopard - HP LaserJet printer setup instructions

1. Upgrade install from Mac OS X v10.4, 10.5:

If updating a Mac using the Snow Leopard DVD, the install process should automatically detect your previous HP printer queue, delete, and then create a new HP printer queue using the latest HP printer drivers included in Snow Leopard.
USB printers:

1. Make sure printer is turnedOnand connected.
2. Open a document to print, and then choose File , Print .
3. Open the Printer pop-up and choose your printer.
4. If you don't see your printer, choose Add Printer , and then selectMore Printersbutton.
5. In the Name column, select the printer, then clickAdd.

Network printers:
You can connect to HP printers on your local network that use Bonjour, IP, and Open Directory, as well as shared printers connected to an Apple Airport base station.
NOTE:Apple does NOT support AppleTalk in new Mac OS X 10.6.

1. Choose File , Print .
2. Open the Printer pop-up menu and choose your printer. It may be in the Nearby Printers submenu.
3. If your printer does not appear, choose Add Printer from the Printer pop-up menu.

If it can't, a dialog appears that lets you specify them. Make sure the settings in that dialog accurately reflect your printer's installed options to enable full functionality.

1. Clean install of Snow Leopard or setting up a new Macintosh with Snow Leopard already installed:

If configuring a new Mac running Snow Leopard or if performing a new or clean install of Snow Leopard:

You will probably have to go to this page to download the new Mac drivers for Snow Leopard to get the full functionality of your All-in-one printer back.

Print functions are generic enough where you don't need to have the most updated driver for it to work. But the scanning functionalities are more complicated.

Find the driver for your computer here:

HP drivers download for PhotoSmart C4480

Delete your old Dell printer in the Print & Fax System Preferences panel. Install a new printer, but select the Mac-installed Samsung CLP-770 Series PS, and presto! You are back in business, complete with duplex printing and toner supply levels. Sweet!

There are apparently incompatibilities between some Xerox drivers and the security-improved Snow Leopard. It seems that many pieces of software (and drivers) relied on not-so-clean techniques to cut corners while operating. These techniques are no longer allowed by Snow Leopard (the same problem afflicts XP SP3, Vista and Seven).

This article lists several problems, explanation and (perhaps) fixes:

Meanwhile, Apple is working to some workarounds too (there is an update linked in the article which may be of interest to you).

As from this link , the drivers for most HP printers are already built-in to Snow Leopard. Thus, they didn't recommend reinstalling driver from your HP printer CD. Here are some excerpts regarding scanning feature on Snow Leopard from the link: Scanning: The Scanning interface is now built into Snow Leopard and supported with the Apple Image Capture application. Instructions follow. NOTE: HP Scan Pro software (from Mac OS X 10.4, 10.5) is not supported in Snow Leopard. The HP icon for HP Device Manager still in the dock after upgrade is not functional and should be removed. NOTE: Scan support from pushing the Scan button on the printer is not supported with this version of the scan interface built into Snow Leopard. Scan functionality is supported by scanning directly from the computer.
** there are methods on how you can scan on Snow Leopard from the link that I've given above. But I'll paste here Method 3:

Method three: Scan from Print & Fax > Printer browser

1. From the Apple menu, choose System Preferences .
2. Click Print & Fax .
3. In the list of printers on the left side of the dialog, select the HP All-in-One to view the options in the Print & Fax window.
4. Click the Scan tab, and then click Open Scanner . The Printer Browser window appears.
5. Click the Scan icon at top right of the toolbar to launch scanning. The scan interface opens. Click Show Details to view settings and options.

Important Gotcha: If the Scan or Print icons do not appear in the Printer Browser window toolbar, you need to delete the current HP printer queue and add a new one, as follows:

1. Close the Printer Browser window to return to the Print & Fax preference pane. Or, go directly to the System Preferences > Print & Fax pane.
2. Select your HP printer in the list on the left.
3. Click the - sign at the bottom of the list to delete the product from the list.
4. Click the + sign at the bottom of the list to add the product back to the list.
5. Select your HP printer, and then click Add to create a new print queue. The next time you open thePrinter Browser window, the Print and Scan icons should appear in the toolbar, providing access to Image Capture.

Generally if your printing postscript, you don't need to update the drivers on a Mac. But there are new drivers available for download on the website here. that said, there is not any difference between the Tiger, Leopard, and Snow Leopard versions of the driver...or much difference in the Linux driver for that matter. If what you have works, don't obsess over upgrading. They all work.

Sir, the Hp LaserJet 2015n printer CANNOT automatically do duplex printing since the printer does not include mechanism and paper storage areas to cycle the paper through the printer a second time and print on the reverse side. Manual duplex printing can be done as follows: Choose duplex printing and remove all sheets after the printing is complete. Turn the sheets over while preserving the orientation and insert them in the paper feed path. I have an HP 1020 laserjet printer which is similar to the 2015.

Hello, sorry you are having problems,
OK, are you sure your printer supports duplex printing and if you are sure you have the right driver installed, this is how you print in duplex mode on a Mac.
Open the document you want to print, Hit cmd+p to get the print dialogue window you should see this:

Notice you have the option of two sided printing in the same line as # of copies.
If you do not have this option in 10.5.6, then you might have the wrong driver, N.B. you must be sure to select the proper driver when you are creating the printer in the Print and Fax preference. Another way to ensure you have the driver properly installed, go to the manufacturer's website and download the Mac Driver Installer and run the installer, delete the printer you created and then re-create the printer again it should auto-recognize the printer..
What is the Printer Make and Model?

Check under the Apple site for this issue. I use Leopard and can copy and print with this machine. I have not tried the fax, however, I assume  it will work. The scanner does NOT work with Apple...at least yet...I am not sure if it is Apple or Canon or both who are at issue for this. As per the post below, the duplex works just fine for me. You may want to consider the possibility of removing the current drivers and reload the one's currently posted by Canon.
Duplex Printing
Apr. 19, 2007

I figured out how to make duplex printing on the MF4150 work! Canon Tech support says that duplex printing is not supported, but they are mistaken.
Here is what you need to do:
1. go to the Canon site and download the latest UFRII driver (v1.5) and install it
2. in the application, go to page setup and select "Format For:" MF4100 Series [this was what I did not realize]
3. then, when you go to print, select the finishing tab, and then select 2-sided printing.
If you skip step 2, and you application defaults to "format for any printer," the 2-sided option will be greyed out. Other printer drivers do not require this, but the Canon driver does.
