Epson GL/2 Mode
Introduction
Epson GL/2 mode features some plotter commands. In this
mode, you can use your printer with plotter applications.
A list of the plotter commands that your printer supports is
included later in this section. Unsupported commands are
ignored.
This mode is available only with ActionLaser 1500 or the
upgraded ActionLaser 1000 with the PCL5/RITech board.
Epson GL/2 mode is similar to GL/2 mode included in the HP
LaserJet III emulation. The table below shows the differences
between Epson GL/2 mode and GL/2 mode included in the
