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.
