[Gimp-print-devel] RFC: hacks to get the SureLab D700 working

[Solomon P. <pi...@sh...>]

Here are the non-XML changes sitting in my tree. The changes in 
stpi_escp2_init_printer() need to be gated off some sort of feature 
flag, perhaps <rollOnly/> in the model.xml file that defines a 
MODEL_ROLL_ONLY capability bit?  Not sure what approach I should take 
here.

The other change disables the special-case in 720x360 resolution so the 
ESC(U command matches what the windows driver sends the printer, but 
there doesn't seem to be any adverse effects to leaving it unchanged.
