Programming Tips
This section provides programming tips concerning specific
considerations for the HP LaserJet 4PJ printer. This
section covers general print job initialization, font metric
calculation, vertical writing, and other issues which are
pertinent to printing Japanese text on the HP LaserJet 4PJ
printer using PCL 5.
General Print Job Initialization
This example demonstrates the general print job
initialization procedure for the HP LaserJet 4PJ printer,
which is slightly different than that used for other HP
LaserJet printers.
Output from pre-LaserJet 4PJ PCL drivers (for example, a
HP LaserJet 4P driver) will only print correctly on the HP
LaserJet 4PJ printer if the default PCL symbol set is set to
a value other than the Japanese Windows 3.1 (Win3.1J)
symbol set. This is because the default PCL text parsing
method is set based on the default PCL symbol set. When
the default PCL symbol set is set to Win3.1J, the default
text parsing method is Shift-JIS parsing; for any other
value, such as Roman-8, the default text parsing method is
1-byte parsing. To set the default PCL symbol set value, use
PJL or the control panel.
The first example given here is nearly identical to the
initialization used for other HP LaserJet 4 family printers.
The only difference is that it includes a PJL command to set
the default PCL symbol set to Roman-8.

The commands in the above example are explained in more
detail in the PCL 5 and PJL technical reference manuals.
