AppleShare IP 6.0: Using Secure Printing

The Print Admin application in AppleShare IP 6.0 provides security features to help network administrators manage access to printers and printer queues. When creating or editing a queue in the Print Admin program you see a security tab. This tab enables the administrator to provide "casual" security features to print queues. The administrator is able to restrict access to specific users and groups, and to require a password.

When specifying which users have access to a queue, the user name must match the owner name for the computer. This is because the owner name is inserted into the postscript document when it is created, using the DSC command %%For. The print server checks to see if the owner name inserted into the PostScript document matches any users in the authorized user list. If these names do not match an error message such as "A PostScript error has occurred. Go to Finder for details" may appear. (There may be no further details in the Finder). Check the print queue's Server Log to see if there is Security Violation error. If so, adjust the names so that they match by changing the owner name to match a current user, or by changing the user name in the Users & Groups list so that it matches the owner name on the user's computer.

Troubleshooting:

To verify that the owner name of the client and the user name on the server match:

1. Open the client's File Sharing control panel (pre Mac OS 8 open the Sharing Setup control panel).

2. Determine the owner name of the computer.

3. Using the ASIP Print Server Admin application, open the queue in question for editing.

4. Verify that one of the names in the list of users approved to print to the queue matches the owner name on the client's workstation.

5. If the entries do not match, change either the owner name on the workstation, or the user's name on the server so that they match.

Some operating systems, including Window NT, use PostScript drivers that do not work with the %%For command as outlined above. On these operating systems using a secure queue is not possible using the default print driver.

Mac OS clients require LaserWriter 8 version 8.6.1 or higher to take advantage of secure PostScript print queues. LaserWriter 8.6.1 and higher are designed for Power Macintosh clients only. (They do not work with computers that have a 68000-family microprocessor.)

If the user is trying to use the secure feature on a Windows computer:

1. Verify that a compatible PostScript driver is installed by printing a document to a file, not the printer.

2. Open the document in a text editor and look for the %%For command.
