Comments about HP LaserJet Printers This section explains some important points that should be considered when using PJL with HP LaserJet 4, LaserJet 5, and Color LaserJet printer families, and the HP LaserJet 6P/6MP printers. Support for the features described in this section varies. HP LaserJet family printers that support a particular feature are listed at the beginning of each feature description. Printer Language Switching Printers supporting printer language switching: HP LaserJet 4, 4M, 4 Plus, 4M Plus, 4V, 4MV, 4Si, 4SiMx, 4ML, 4P, 4MP, 4PJ, 4LJ Pro, 4000 series, 5, 5M, 5P, 5MP, 6P, 6MP, 5Si, 5SiMx, 5Si Mopier, HP Color LaserJet, HP Color LaserJet 5, 5M Printers that perform context switching automatically switch printer languages when both of the following conditions are met: The PERSONALITY variable is set to AUTO. The print job contains printable data but does not contain an ENTER command immediately before the printable data. Note HP LaserJet 4PJ and 4LJ Pro printers perform implicit language switching, but not context switching. HP LaserJet 4V and 4MV printers cannot context-switch into the ESC/P language-use explicit switching instead. Under these conditions, the printer samples the incoming printable data and looks for indications of a particular printing language. Once it recognizes the printer language, the printer backs up to the beginning of the sampled print data and switches to the printer language determined to be most appropriate. Then the printer begins to parse the data in the newly selected printer language. Feature Support A-29
