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).
