The LaserWriter 8 driver that dists to the Desktop Publishing stations offers several features not found in the standard LaserWriter driver. The major enhancement is support for "Postscript Level 2" printers. The original Postscript page description language included basic support for laser printers (multiple copies, for example), but as laser printers become more complex, "Level2 " postscript was developed to accomodate new printer features. In addition to other enhancements, Level 2 Postscript allows a computer to take advantage of a specific printer's options (automatic double-sided printing, for example). LaserWriter 8.0 was the first version of the LaserWriter driver that included support for Postscript Level 2. The LaserWriter 8 driver uses PostScript Printer Description (PPD) files to determine the characteristics of the printers it uses. PPD files contain information about individual PostScript printers. For example, PPD files describe the paper-handling capabilities of printers: the number of paper trays, their capacity, and the paper sizes they handle. To take full advantage of a printer's features using the LaserWriter 8 driver, click the Setup button in the Chooser when selecting your printer for the first time, or after installing an additional option. This procedure causes the LaserWriter driver to query the printer for its characteristics and associate a particular PPD file with the printer. If the automatic setup does not work, the LaserWriter driver will use the "generic" Postscript printer PPD.

LaserWriter 8 is disted to the Desktop Publishing stations so that they can take advantage of Postscript Level 2. Our cluster printers (controled by the Novel PC Server) do not need to use Postscript Level 2, but printers such as those found in the

• The PrintShop
• Installing/Removing Fonts
• TrueType, Postscript, and Bitmap Fonts
• Adding Fonts to Public Macs
• Screen and Printer Fonts

• Creating EPS files with the All option selected in the Font Inclusion pop-up menu in the EPS dialog box can result in very large files. If you include all fonts in an EPS file and save the file with the Unlimited Downloadable Fonts option selected, an extremely large file may be created.
• If you create an EPS file with no fonts included and open the document, fonts in the document appear on your screen, but Courier may be substituted when you print.
• When you create EPS files with preview information included, other applications that create their own PostScript code may not display the EPS file accurately on the screen.

All LaserWriter Printers:

• The LaserWriter 8 driver allows some printers to print using a larger imageable print area on the page. If your printer does so, you may find that text in some documents reflows or is clipped to fit the new imageable area. To maintain your document format when printing to different printer models, deselect the Larger Print Area option in the Page Setup Options dialog box.
• Some older printers with small amounts of memory will not print documents containing large numbers of fonts unless the Unlimited Downloadable Fonts option is selected in the Page Setup Options dialog box. If a document using multiple fonts doesn't print using the LaserWriter 8 driver, try selecting Unlimited Downloadable Fonts in the Page Setup Options dialog box and print again.
• Printing multiple documents with the Finder may not work if the documents have been created by different application programs.
• If you encounter a time-out (PostScript error -8993) when printing multiple copies of large and complex documents in the background, print the documents one at a time or select foreground printing to avoid this problem.

LaserWriter IIg and IIf:

• When you select paper sources from the First From and Remaining From pop-up menus in the Print dialog box, selecting Manual Feed for either source sets the driver to print the first page from the manual feed tray.
• The US Legal paper size has been changed on some LaserWriter IIf/IIg printers to be more compatible with other Apple LaserWriter printers. If your legal-sized documents no longer fit on the page, select Larger Print Area in the Page Setup Options dialog box.
• Some form-printing applications cannot print forms using the Layout settings in the Page Setup dialog box.

LaserWriter II NT and II NTX:

• If you select both the Smooth Graphics and the Invert Image options in the Page Setup Options dialog box, a PostScript error results.
• Do not use the B5 tray to print envelopes on a LaserWriter II NT. Use the letter tray instead.

LaserWriter Pro 600 and 630:

• You cannot use Auto Select as the Paper Source in the Print dialog box to print envelopes from the optional envelope feeder.
• When you print at a resolution of 600 dots per inch (dpi), bitmapped images may appear with lines across the image.

LaserWriter Pro 810:

• With some graphics applications, bitmapped graphics will be reduced by 25% in size when printed with the Precision Bitmap Alignment option in the Page Setup Options dialog box.
• When you create a PostScript file with a LaserWriter Pro 810 selected as the printer and send the file to a printer that uses PostScript Level 1, a PostScript error will occur.

LaserWriter 16/600 PS:

• If Tray Switching is turned on and you have installed the optional 500-sheet feeder, and it contains the same paper size as the 250-sheet feeder, you should set up the driver to use the 500-sheet feeder as the preferred paper source for optimal printing performance. See Chapter 5 in the manual that came with your printer for instructions on selecting the 500-sheet feeder as the preferred paper source.
