usage getStatus and getStatuses functions about driver HOT 3 CLOSED

@saitahmety the printer must return all four statuses in this method if the memory switch 1-3 is set to "receive buffer full" from "receive buffer full or offline", as you can see here mike42/escpos-php#43 (comment)

"receive buffer full" => printer always responds
"receive buffer full or offline" => printer does not respond in some situations such as cover open or paper out

After changing this memory switch, it always returns successfully.

But there is still a bug because the promise is not rejected when "receive buffer full or offline" is set, so I created a pull #46 to solve it

from driver.

Oh I got it, thank you so much @felipeguimaraes2 , solved on this #46

from driver.

Moreover,
getStatuses function does not return response when at least one of these 4 statuses is undefined.
Because of "if (buffer.length < 4)" condition.

But I want to get the other statuses even if the byte data of one status is undefined.
When I remove "if (buffer.length < 4)" condition
output like this,

Can we remove this condition ?

Please revision code and release NPM. It's important for my project.
Thanks for this awesome project.
