HP LaserJet 4P
and 4MP Printers
The HP LaserJet 4P printer is the follow-on to the HP
LaserJet IIIP printer. The HP LaserJet 4MP printer is the
multi-platform (PostScript) version of the 4P printer. PCL
operation and the internal fonts in these two printers are
identical to that of the HP LaserJet 4ML printer. The 4P
and 4MP printers have a control panel unlike the 4L and
4ML printers. Refer to Table 1-1, PCL Feature Support
Matrix, for the commands these printers support and to
Chapter 3, “Internal Typefaces/Fonts and Symbol Sets,” for
font support information.
