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).
