[Bug 37554] Re: Konica Minolta PagePro 1300W USB Printing problem

[Martin Pitt]

Oliver, thanks for your investigations. Indeed the break won't be
reached, since !(0 && something) is always true.

However, from reading lp.h, it says

  #define LP_PERRORP      0x08  /* unchanged input, active low */

so if that bit is zero, it means 'yes', and thus the printer reports an
error condition. I'll talk with upstream about this.
