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.
Note
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.
