Chapter 2 • Getting Started

Use InterPrint to print a file from your Macintosh on any UNIX® PostScript printer that responds to the LPR command.

◊ PostScript is a popular page description language developed by Adobe Systems, Inc. that allows a computer to translate pages in a device-independent manner.
◊ LPR is a UNIX command used to print a file to a printer or another output device. It is also the protocol used to address a UNIX printer.

Before using InterPrint, you must install it on your Macintosh and configure it. After it is installed and configured, you can select InterPrint in the Chooser and print from any application as if you were printing directly to a LaserWriter®.

InterPrint includes two utility applications, LPR Monitor and LPR Send. LPR Monitor allows you to monitor and remove your print jobs after they have been sent to a queue. LPR Send is a System 7 drag-and-drop application you can use to print your PostScript or text files. See Chapter 3, InterPrint Utilities, for more information on LPR Send and LPR Monitor.

◊ You can send your file to other output devices such as display screens. However, throughout this manual, we use the term printer to represent all output devices.

2.1 Installing InterPrint

The Apple Installer utility is included with this package to simplify installation of InterPrint. InterPrint automatically installs or upgrades MacTCP during installation, if necessary. To configure MacTCP after installation, see the section Configuring MacTCP in the book About Networking: A Guide to TCP/IP and MacTCP.

The Easy Install dialog, shown below, contains the following options:

Install • begins Easy Install.
Eject Disk •
ejects the current disk (displayed at the bottom of the Installer window).
Switch Disk •
changes the disk where InterPrint will be installed.
Customize
• allows you to install InterPrint based on your own specific needs.
Help
• gives installation information.
Quit
• cancels installation.

For more information on the Customize option of the Installer, see the InterPrint Release Notes included on the InterPrint Installation disk.

To load InterPrint to your hard drive using the Apple Installer utility:

1.
Insert the InterPrint Installation disk into your disk drive.

2.
Double-click the Installer icon in the InterPrint Installer window.

2.2  Configuring InterPrint

When you configure InterPrint, you need to specify certain user preferences, such as your user name and host name. You also designate which LPR print server your Macintosh will direct files to for printing. For each printer, you assign a name that identifies it and enables it to be selected in the Chooser. By entering valid print queue names, you configure printers to use with InterPrint. The following sections guide you in configuring InterPrint.

◊ A print queue is a directory that holds output designated for the printer until the printer can receive it. By extension, it is the name by which you access a printer. In most references in this manual, the term printer is used to include the print queue.

◊ Because InterPrint does not use any AppleTalk protocols commonly associated with the Chooser, you do not need to select an AppleTalk Zone in the Chooser dialog. InterPrint also does not require AppleTalk to be active.

When configuring for InterPrint, use the InterPrint pop-up menu, shown below, which is labeled Add Queue… in the Chooser.

This menu contains the following items:

Add Queue…
• allows you to add printers to InterPrint’s LPR Queue list (see Section 2.2.2,  Adding an LPR Queue).

Remove Queue…
• deletes the selected printer from the LPR Queue list (see Section 2.2.3,  Removing an LPR Queue).

Edit Queue…
• allows you to edit information on the selected printer (see Section 2.2.4,  Editing an LPR Queue). 

Preferences…
• sets user information for InterPrint (see Section 2.2.1,  Setting your InterPrint Preferences).

Font Query List…
• allows you to specify what PostScript fonts are installed on a printer (see Section 2.2.5,  Using the Font Query List).

Valid Character…
• allows you to set which characters are sent to the printer as ASCII and which are converted to escape sequences (see Appendix B, Troubleshooting).

◊ Typically, you will not need to use this dialog. 

Background Printing
• when checked, allows you to perform other tasks while printing occurs in the background.

◊ This item is not available under System 6 running Finder, but is available if you are running MultiFinder.

About InterPrint™…
• gives information about InterPrint, including your product serial number.

2.2.1 Setting your InterPrint Preferences

To configure InterPrint preferences:

1.
Select Preferences… from the InterPrint pop-up menu.

√ The Preferences dialog, shown below, is displayed.

2.
In the User Name field, type your user login for the server that you send files from.

3.
In the Host Name field, type the name of the server that you send files from.

◊ The Host Name must be a valid IP address or host name that resolves to a valid IP address and must be recognized by the print server as a valid source of print requests.

4.
Check Print Banner Pages if you want an introductory descriptive page to be printed along with your document. The contents of this page depend on the LPD (line printer daemon) being used.

5.
Check Send Mail When Printed if you want to receive a mail message notifying you when your document has been printed or if printing has failed.

◊ Mail will be sent to User Name at Host Name. In the figure above, mail will be sent to kiki@intercon.com.

◊ Ask your System Administrator if Print Banner Pages and Send Mail When Printed are available on your server and are turned on.

6.
Click OK to save your preferences. (Or click Cancel to close the dialog without saving your changes.)

2.2.2  Adding an LPR Queue

From the InterPrint pop-up menu, select Add Queue… to add a printer to the LPR Queue list.

To add an LPR queue:

1.
Select Add Queue… from the InterPrint pop-up menu, repeated below.

√ The Add Queue dialog, shown below, is displayed.

2.
In the Queue Name field, name the queue.

◊ Although all characters are acceptable in the Queue Name field, we suggest you use something similar to the name of your printer for easy reference.

3.
In the Server field, type the name of the host (typically a UNIX host) that is acting as your print server.

◊ For a host to be used as a server, it must be running LPD or a functional equivalent that conforms to RFC1179, Berkeley's initial LPR implementation.

4.
In the Queue field, type the printer’s official print queue.

◊ The print queue for your printer can usually be found in the /etc/printcap file on the server. Or ask your System Administrator for the official print queue.

5.
Click OK to save your changes. (Or click Cancel to close the dialog without saving your changes.)

√ The printer you added appears in the LPR Queue list in the Chooser, shown below.

4.
Click OK to save your changes. (Or click Cancel to close the dialog without saving your changes.)

2.2.5 Using the Font Query List

When you use InterPrint, there is no way to obtain font information directly from a printer; however, the printer driver needs to know what is available on the printer. Select Font Query List… from the InterPrint pop-up menu to identify the fonts on each printer configured for InterPrint. The list contains the 35 PostScript fonts most commonly found on laser printers. You can add fonts to the list or remove them to customize the list for each printer.

◊ Ask your System Administrator for the list of fonts that are actually installed on each printer you configure. If your entries in the Font Query List do not match the fonts installed on the printer, documents may print with incorrect or bit-mapped fonts.

To edit the Font Query List:

1.
Highlight a print queue from the LPR Queue list in the Chooser.

◊ Be sure to highlight the correct queue. You cannot revert automatically to the previous font list.

2.
Select Font Query List… from the InterPrint pop-up menu.

√ The Font Query List, shown below, is displayed, with the printer’s queue name at the top of the dialog.

3.
To remove a font, select it and click Remove.

√ The font name is removed from the list.

4.
To add a font, type the proper PostScript font name in the field provided and click Add.

√ The font name is added to the list.

5.
Click Done to save your changes and close the dialog.
◊ If you do not select a print queue before selecting Font Query List…, the dialog contains a list of default fonts. You can customize this list so it becomes the default for all new queues.
