Enter HP-GL/2 Mode Command The Enter HP-GL/2 Mode command causes the printer to interpret data as HP-GL/2 commands instead of PCL commands. Three new parameters are added: one enables stand-alone plotter mode (?%-1B), and the other two affect the coordinate system and pen position when switching into HP-GL/2 (?%2B and ?%3B). ?%#B # = -1 - Stand-alone plotter mode (single context) 0 - Use previous HP-GL/2 pen position 1 - Use current PCL CAP 2 - Use current PCL dot coordinate system and old HP-GL/2 pen position 3 - Use PCL dot coordinate system and the current PCL CAP Default = 0 Range = -1 to 3 HP-GL/2 mode remains in effect until a Start Raster command (?*r#A), Reset (?E), UEL command (?%-12345X), or power-on. In stand-alone plotter mode (?%-1B), only a single context can be used (HP-GL/2 and PCL cannot be merged on the same page). A value field of 1 or 3 sets the HP-GL/2 pen position and the label carriage return point to the current PCL CAP. A value field of 2 or 3 transfers the current PCL dot coordinate system, including the PCL origin and axes; the coordinate system thus established is independent of the positions of P1 and P2. This command cannot be executed from display functions mode or within a binary data transfer. HP-GL/2 ignores this command. 2-86 Printer-Specific Differences ENWW
