Note Print Quality Command This command determines print quality and speed. ?*o#Q # = -1 - EconoFast 0 - Normal quality 1 - Best/Presentation graphics Default = 0 Range = -1, 0, 1 EconoFast prints black text at 300 dpi. When transparency or glossy media is loaded, the printer automatically adjusts the media type to Transparency and the print quality to Presentation graphics, regardless of the language or remote-panel selection. The Media Type and Print Quality commands always override remote control panel settings if the printer detects a different type of media than was requested. It may override these commands and the remote control panel settings. This command must be sent at the beginning of the page before any printable data; otherwise, when the command is received, the current page is closed and printed. 2-88 Printer-Specific Differences ENWW
