Companies like Hewlett-Packard, Apple, and IBM purchase
laser printer engines from companies like Ricoh and Canon.
The engines they purchase have all the necessary parts in
place. The laser manufacturer designs the computer and software
that goes into the laser printer. Because different printer
manufacturers often use the same type of printer engine,
the features that they add to those engines determine the
differences among laser printers.Dot-matrix printers don't
normally have enough memory for downloaded fonts. In graphics
mode, they print a band or strip at a time, so they need
just enough memory to hold the graphics data representing
the strip. Normally, a dot-matrix printer has around 32K
of memory. This is enough to hold a few downloaded symbols
but not downloaded fonts.
In a standard laser printer, the amount of memory is 512K
expandable to 4.5M. Typically, character laser printers
do not need more memory unless you need many character fonts
downloaded at one time. Object-mode laser printers typically
come with 2M of memory, although the maximum can be 12M.
The typical maximum is 4M, however. More memory increases
the number of fonts available and usually speeds up the
printing process.
