Printing to a printer on a Windows XP PC from a Mac running 10.4.x
This guide will show you how to print from a Mac running 10.4.x to a printer attached to a Windows XP PC. In this guide I am using an HP PhotoSmart P1000 printer on a XP PC and printing from a Mac running 10.4.x
On the Windows XP PC, enable printer sharing from an account which has administrative privileges and has a username and password used for access.
Start -> Control Panel -> Printers and Faxes
.
Double click to open.
Right click and select Sharing...
You will be presented with the following window.
Check Share this printer
Windows XP will automatically give it a name, as you can see in this example it has given the name hpphotos if you wish you can use a more memorable name, but ensure it has no spaces. In this example I have given it the name PhotoSmart. Make a note of the name.
Click OK
The printer icon has now changed and has a hand underneath to indicate it is now shared.
On the Mac double click Printer Setup Utility in the Utilities folder in Applications.
You will now be faced with a new window.
In this example you can see the other printers on my Mac, if this is the first printer you are setting up there will be no printers listed.
Click the Add button.
Click the More Printers... button.
This will bring up the following dialogue box.
Change the dropdown box from the default (in this case Bluetooth) to Windows Printing.
Remember to ignore such things as hp photosmart which would only apply if you connecting the printer directly to the Mac.
In the new dialogue you can see that the Mac has found the Windows Workgroup which in this example is called Westerncc. Your workgroup may be called MSHOME, WORKGROUP or something else. Select your workgroup and click the Choose button.
You can now see the XP PC (called Argostoli in this example) and another computer in that Workgroup.
Select the correct computer (in this example called Argostoli and click Choose.
You will now face an authentication dialogue.
For Name enter the Windows User account username.
For the Password ener the Windows User account password.
Check the Remember this password in my keychain box to avoid having to enter the password again.
Click OK
You can now see the printer attached to the XP PC.
Select the printer but do not click Add as you need to change the Printer Model.
Under Printer Model select HP.
Select your printer from the list.
In this example I have selected HP Photosmart P1000 - Gimp-Print v5.0.0-beta2. You will notice that I am using the Gimp-Print driver as the supplied HP driver does not work when the printer is shared from another computer. You may need to use a third-party driver such as the HPIJS drivers or the Gimp-Print drivers, but this is not the case with all printers.
Click Add.
Your printer is now added to your printer list and can be used from applications. Remember that your Windows XP PC must be switched on in order to allow the Mac to print to it.
