При вводе dev / usb / lp0 он говорит: «Нет такого файла или каталога»

Попробуйте использовать SUDO . Страница MAN для escputil также говорит об этой ошибке как об известной ошибке, попробуйте еще раз ввести команду, которая должна решить проблему.

   USB-connected printers sometimes fail to identify or return ink levels.
   You may have to repeat the command.  This is probably a timing issue in
   escputil, not a flaw in the printer.

   Anything  requiring bidirectional communication with the printer (iden-
   tify, ink levels, or head  alignment  without  specifying  the  printer
   model)  requires  read/write  access  to  the printer port (for example
   /dev/lp0).  This may require these operations to be performed as  root.
   In  addition,  kernel  support is required for bidirectional communica-
   tion.   For  Linux  version  2.2,  CONFIG_PRINTER_READBACK  should   be
   enabled; this is called CONFIG_PARPORT_1284 on 2.4 and later kernels.

   If  the  printer  is performing self-test or head cleaning on power up,
   the identify and ink level commands will time out, although the printer
   successfully  receives  the command.  The command will need to be reis-
   sued when the printer is quiescent.
