2-12 Printer-Specific Differences
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).
