HP LaserJet 4ML Printer
The HP LaserJet 4ML printer is similar to the HP LaserJet 4L printer,
however, the 4ML includes PostScript and a LocalTalk I/O for printing
in the Macintosh environment. The HP LaserJet 4ML printer also
includes some new PCL features: print model logical operation
(ROP3) and pixel placement, as described on the following pages.
The HP LaserJet 4ML supports the typefaces that the HP LaserJet 4
printer supports. Several of the typefaces in the HP LaserJet 4ML
printer have additional support for the Latin 2 and Latin 5 symbol sets
(refer to Chapter 3, “Internal Typefaces/Fonts and Symbol Sets,” for
complete font support information). The Line Printer bitmap font is not
present on the HP LaserJet 4L printer.
