8. Known Issues
1. The first line of the characters on the printed receipt is too light. (before version
2007-10-10)
The motor of the printer is quite slow when printing the first line of a receipt, so that the time between
two heat strobes are very long and the characters printed seems to be light. However, if the first line
is left blank (only CR) then the receipt will be alright. This problem has been resolved in later release
versions. (It only occurs in the versions before 2007-10-10)
2. Printing flushes the bootloader if the P25 printer series is in download Mode (before
version 2008-06-02)
Press Feed + Power key, the P25 printer series enters into download Mode, but if sending printing
data instead of download data, the printing flushed P25’s bootloader, (This problem only occurs
before bootloader version
2008-06-02. after that version, this problem has solved.)
3. After downloading a new font, printing data would cause the paper to burn.
After downloading a new font file, press Mode + Feed to do a self test caused the paper to burn
severely. This was caused by using an old version of the Device Manager (before Device Manager
version
2007-12-26) and font designed for the new version of the Device Manager.(2007-12-03 <=
firmware version < 2008-06-20), After version 2008-06-20, font file name extension was changed
from “ . “font to” .ap2”, and the old version of the Device Manager did not support downloading of .ap2
files, so the operation failed.
