摘要： An improved color EP (laser) printer is provided for use in high humidity conditions. A humidity sensing circuit determines if the print quality might be degraded due to environmental conditions, using a resistively sensing circuit, or a humidity sensor. If the print quality would likely be degraded, the invention is able to enhance toner transfer by printing supplemental process black toner dots underlaying standard black toner dots at predetermined pixel locations in the bitmap of a print job. This assumes that the black printing station is the “last” station along the travel of the intermediate transfer member. Other colors, could be used for the supplemental toner dots.

摘要： A printer is provided which has a special Emulation Manager function as well as a “code sniffer” function, in which print data received is sent to a code sniffer buffer. A code sniffer function automatically determines the type of emulator that should be called to perform the interpretation or rendering of this print job, and if the code sniffer determines that the correct emulator is PostScript, then the code sniffer scans the data for any “special tokens.” If a special token is found, the PostScript emulator determines if the special token string data is part of a PostScript comment. If it is in the correct format, then the PostScript emulator sets the “mode flag” to the “MacBinary” state, and the code sniffer ceases any further filtering of control characters and disables any change of emulator command that may be received during this print job. The rest of the print job is then interpreted as RAW binary data by the PostScript emulator, until a “UEL” string is encountered.
