<1Bh><0Dh>mode 

• 

This command enables you to switch emulation mode or to reset the printer. 

• 

Change emulation mode by setting 

mode

 to the appropriate letter or pair of letters.  Set 

mode

 to ‘D’ to 

switch to Diablo mode, ‘H’ to switch to LaserJet mode, ‘I’ to switch to IBM Proprinter XL mode, 'AB' 
to switch to BR-Script Batch mode, 'AI' to switch BR-Script Interactive mode, 'GL' to switch to HP-GL 
mode.  

• 

If you set 

mode

 to ‘E’ in Epson FX-850 mode , a printer reset is performed. 

• 

If you set 

mode

 to ‘FD’, to reset the printer to its factory default settings, LaserJet mode (the factory 

default emulation mode) is selected and the LaserJet factory default environment is restored.  For a list 
of the factory default settings see the sub-section “Factory default environment” in Chapter 2 "PCL" 
of this manual. 

• 

On receiving this command the printer prints any remaining data and performs a page eject (unless the 
current page is blank).  The newly selected emulation mode’s default settings come into effect, except 
when 

mode

 is set to ‘FD’.
