Rollback
Same practical path as the A1: Handy for a hosted older package, or microSD for an offline package. The A1 mini notes for 01.08.01.00 say an offline update from 01.04.00.00 or earlier can garble characters — repeat the offline update or put the printer online. On 01.06.00.00 and older, an offline update fails while AMS, AMS 2 Pro, or AMS HT is connected.
