HP LaserJet 4Si Printer

The HP LaserJet 4Si printer is the follow-on to the HP LaserJet IIISi printer. The HP LaserJet 4Si printer contains many new PCL features over the HP LaserJet IIISi. PCL support for the HP LaserJet 4Si printer is identical to the HP LaserJet 4 printer except for the addition of the duplex feature, dual output bin (see Table 1-1) and resource saving.

Like the HP LaserJet IIISi printer, the HP LaserJet 4Si supports the HP LaserJet IIISi features listed in Table 2-1 with two exceptions. First, is that the HP LaserJet 4Si does not support ITC Zapf Dingbats. Font support for the HP LaserJet 4Si is identical to the HP LaserJet 4 printer (refer to Chapter 3, “Internal Typefaces/Fonts and Symbol Sets,” for complete font support information). The other exception concerns job separation. The PCL Job Separation command is not supported. The HP LaserJet 4Si printer handles job separation through the control panel. If a PCL Job Separation command is received by the printer it will be ignored. Refer to the HP LaserJet 4Si User’s Manual (part number C2010-90901) for additional information.

Resource saving, a new feature in the HP LaserJet 4Si printer, allows saving information for the current language (PCL or PostScript) when switching to the other language. If resource saving is enabled (from the control panel or PJL; no PCL commands are required for this operation), all the permanent fonts, macros, and user-defined patterns plus some other miscellaneous data is saved in a reserved portion of printer memory. This data is stored until

the language is enabled again. When the language is re-enabled, the stored data will be made available for use.
