ChemDraw User's Manual - CambridgeSoft

QuickDraw is the graphical format that issupported by the Macintosh Operating System.Every printer that supports the MacOS can convertQuickDraw representations into printed output.However, QuickDraw does not support somefeatures (for example, high-resolution printing) thatare available only on some printers.If you are transferring information to another applicationfrom which you print ChemDraw pictures,you should consider including PostScriptcommands and the ChemDraw LaserPrep File withthe pictures. For information about special situationsto consider, see “Transferring PostScript(Macintosh)” on page 195.Optimize Pictures for High-ResolutionNon-PostScript PrintingThe Macintosh High Resolution Clipboardsupports high-resolution printers. Most applicationssupport the High Resolution Clipboard.Because this was not always the case in the past, thispreference continues to be available for users toturn off if an application being used does notsupport the High Resolution Clipboard.If you are unsure if the application uses a HighResolution Clipboard, try transferring pictures withthis check box selected and deselected, and seewhich picture prints with higher quality.If you are printing to a non-PostScript printer, deselectInclude ChemDraw LaserPrep and IncludePostScript to reduce the size of each picture. Donot deselect this option if the document will ever beprinted to a PostScript printer.Printers that use the PostScript page definitionlanguage use the PostScript representation. ThePostScript representation describes objects byusing mathematical shapes that can be preciselyimaged at whatever resolution is used by yourprinter. The PostScript representation created byChemDraw is composed of two parts, the Post-Script commands and the ChemDraw Laser Prep.The ChemDraw Laser Prep contains specificinstructions that enable the printer to interpret thePostScript commands contained in a ChemDrawdocument.Include PostScriptTo transfer ChemDraw pictures to anotherdocument that will be printed on a PostScriptprinter:1. From the File menu, choose Preferences.2. Click Include PostScript.3. Click OK.When Include PostScript is deselected, no Post-Script commands are generated. This usually resultsin lower quality printing, particularly of drawingscut and pasted into other applications. However,because the representation used for printing whenInclude PostScript is not selected is the same as thatused for drawing to the screen, better correspondencebetween the screen and printed output maybe observed.For more information, see “Transferring PostScript(Macintosh)” on page 195.Include ChemDraw Laser PrepSelecting the include ChemDraw Laser Prep allowsyou to print to a printer that cannot be initializedusing ChemDraw. If you create drawings with thisoption off, they will not print on PostScript printerswithout the use of ChemDraw.To Include ChemDraw Laser Prep:1. From the File menu, choose Preferences.2. Click Include ChemDraw Laser Prep.3. Click OK.NOTE: When you select Include ChemDraw Laser Prep,you should also select Include PostScript.ChemDraw 9 ChemDraw Basics • 29Printing
