Hi,
 
I'm using Browser Print and a GK420d printer. I've stored a format, "TRIAL.ZPL" on the E: drive. I want to send a command from my javascript through Browser Print that tells me if my format is there. I know I can use the following in ZPLII:
 
^XA
^HWE:TRIAL.ZPL
^XZ
 
but that returns a multiline string like this:
  - DIR E:TRIAL.ZPL   * E:TRIAL.ZPL      50                    
-   1516624 bytes free E: ONBOARD FLASH
which is a pain to parse. I'd like a Boolean return instead. Is there a command (SGD, ZPL, etc.) that will do that?
