If you want to use an HP-GL application on a PostScript port, you must explicitly set up that printer port for HP-GL data or enable Adobe IntelliSelect automatic language selection. If you want to use a PCL5 application, you must enable automatic language selection. Refer to the Phaser 300X Drivers and Utilities Printing Reference. If automatic language selection is enabled, you can change back and forth between HP-GL, PostScript, and PCL5 regardless of the default language. You can also change the default language so that the next time you turn on the printer, it expects to receive HP-GL, PostScript, or PCL5 data on a specific port. The printer has default values for the HP-GL parameters, such as pen color and pen width. However, you can change these values. Refer to "Changing the HP-GL default settings" for more information.
Switching printer languages The Phaser 300X printer can be set to automatically sense the language of the print job and process it accordingly. This Adobe IntelliSelect automatic language selection feature allows you to send jobs to the printer in different languages. With automatic language selection enabled, you can automatically switch between all three languages: PostScript, HP-GL, and PCL5. You can also set up any printer port to receive one language only. If you set up a port to receive a particular language only, that port will only accept jobs of that type. To enable or disable automatic language selection on a port, send the appropriate PostScript utility file to the printer. For more information, see the Phaser 300X Drivers and Utilities Printing Reference. Note:This utility file is best used only if you plan to switch between all three languages or if you will mostly be using PCL5. Printing with PCL5 In PCL5 mode (HP LaserJet III emulation), the printer supports Courier, Times, and Universe typefaces in the following styles and stroke weights: bold medium, italic medium, and bold italic. To use a PCL5 application, you must customize PCL5 and set up a printer port with the appropriate automatic language selection utility file (refer to the Phaser 300X Drivers and Utilities Printing Reference for information about utility files).
