The devicetype must contain at least one character, and only the first 31 characters are used. If an invalid character ($00 is not treated as an invalid character) is contained in the devicetype, the printer will ignore the escape sequence. If the printer encounters the NULL ($00) character in the devicetype, it uses the NULL character to terminate the device type. All the characters preceding the NULL will be used as the devicetype. If the device type is invalid then the printer's type is not changed. The default device type for PCL is "HP LaserJet 4" and for PostScript is "LaserWriter". ENWW Printer-Specific Differences 2-9
