HP terminals

Gnuplot provides two generic terminals for old Hewlett-Packard pen plotters and printers. The HPGL printer control language was introduced in 1974 and is recognized by many plotters and printers from that era. See set term hpgl. The PCL5 printer control language was introduced in 1990 and became standard for many devices by HP and others. See set term pcl5. Both of these terminals are included in gnuplot by default.

There are also legacy terminals to support specific plotters (hp26 hp2648), inkjet printers (hp500c), and early laserjet printers (hplj hpljii). These are not included unless you modify the source code file term.h.
