Note • When using a multitask OS, status queries and responses may not be transferred
immediately from your application to the printer and vice versa. So write your program in
such a way that it repeats the query if it gets a timeout or an invalid reply. Good practice is to
ask once every ten seconds, five times before giving up.
Note • You should construct your application in such a way so as not to request status while
printing, as this can result in loss of data.
