Note: These driver installation instructions are valid for Windows NT 3.x only; for information about driver installation for Windows NT 4.x, contact Tektronix technical support.

These instructions assume a basic familiarity with Windows NT operation and terminology. For additional information about Windows NT, refer to your Microsoft Windows NT documentation.

1. Start your system with Windows NT.

2. If your computer has an Intel-compatible processor, such as the Intel I386, go on to Step 3.

   If your computer is a MIPS, Alpha, or Power PC, you need to edit the PRINTER.INF file on the printer's CD-ROM or software for Windows diskette.

   Note: If you are not sure of the number of fonts installed in your printer, the printer's startup page lists the number of fonts installed. See your printer's user documentation for instructions on printing the startup page.

   1. The printer's CD-ROM and software for Windows diskette are read-only (write-protected). To edit the PRINTER.INF file, copy the following files from the top level of either CD-ROM or diskette to a new, formatted floppy diskette.
      Place all three files at the top (root) level of the new diskette.

      TEK1
      PRINTER.INF
      TK550171.PPD (for the standard 17-font version of the printer)
      TK550391.PPD (for the printer's extended features option with 39 fonts)

      Note: The file names given in this example are for a Phaser 550 printer, if you are installing a different Tektronix printer, such as a Phaser 350 printer, use the appropriate files for that printer.

      ---

   2. Open the copy of the PRINTER.INF file on the new diskette in a text editor such as Notepad.

   3. Locate the following section in the PRINTER.INF file:
      [ProductType]
      STF_PLATFORM = I386

   4. Replace the I386 with either MIPS (for a MIPS platform), Alpha (for an Alpha platform), or ppc (for a Power PC).

   5. Save the PRINTER.INF file, and go on to Step 3.

3. From the Main window, double-click on the Print Manager icon.

4. If you have a PostScript printer driver installed, go on to Step 5. If you do not have a PostScript printer driver installed, install one now (you need your original Windows NT setup diskettes or CD-ROM to do this). You need a PostScript printer driver installed because the driver files are required to complete the Tektronix printer installation.
   1. From the Printer menu, select Create Printer; the Create Printer dialog box appears.

   2. Under Driver, scroll through the list and select a PostScript printer, such as the Apple LaserWriter NT, and click OK.

   3. Follow the on-line instructions to install the driver files from your Windows NT CD-ROM or diskettes.

5. Install the Tektronix printer. From the Printer menu, select Create Printer; the Create Printer dialog box appears.

6. Under Driver, scroll to the end of the list and select Other; the Install Driver dialog box appears.

7. When prompted, do one of the following.
   • If you are using the printer's CD-ROM: Type in the CD-ROM drive location. Click OK; the Select Driver dialog box appears.

   • If you are using the printer's software for Windows diskette: Type in the disk drive location of the diskette. Click OK; the Select Driver dialog box appears.

   • If you are using an edited copy of the PRINTER.INF file from Step 2: Type in the disk drive location of the diskette. Click OK; the Select Driver dialog box appears.

8. Under Printer Driver, choose your printer from the list, then click OK. For example, if you are installing a Phaser 550 printer:
   • Select Tektronix Phaser 550 if you have the standard version of the printer with 17 fonts.

   • Select Tektronix Phaser 550 with 1200 dpi if you have the printer's extended features option with 39 fonts.

     Note: If you are not sure of the number of fonts installed in your printer, the printer's startup page lists the number of fonts installed. See your printer's user documentation for instructions on printing the startup page.

9. In the Windows NT Setup dialog box, type in the same path you used in Step 7 (for example, B:). Click Continue; the Noncritical Error dialog box appears.

10. When you are prompted for the location of the PSCRPTUI.DLL file and the PSCRIPT.DLL file, click Ignore. (These files were installed in the procedure in Step 4 or were already installed.)

11. When the Create Printer dialog box appears, fill in the other fields as desired, then click OK; the PostScript Printer Setup dialog box appears.

12. Select options in the PostScript Printer Setup dialog box. Enabling the Use Printer Halftoning option is recommended. Then click OK; the Windows NT Setup dialog box appears.

13. If you installed a PostScript printer in Step 4, follow this procedure to delete it. (Now that the Tektronix printer is installed, this printer is no longer needed.)
    1. Select the printer you want to remove.

    2. From the Printer menu, select Remove Printer.

    3. At the prompt, click OK to remove the selected printer.
