The proposed algorithm allows the printer to estimate the remaining media and thus, the printer, could
inform of it allowing the customer to check if their job fits on the loaded roll or calculate how many copies
they can do among other things.
The presented disclosure’s algorithm to estimate the remaining media length in the loaded roll without
adding any new sensor more than the currently present in our printers. This allows to deploy the solution
via firmware update to all our printers.
The solution estimates the remaining length of the loaded media roll without the need if tracking it using
a barcode or reference on the media. Then the customer could recall the estimated remaining media at
any moment after loading the roll to perform his job in a more efficient way.
