printing bitmap doesn't work in example

[eugeniop]

Got the Adafruit thermal printer. The example supplied works perfectly except for the 2 printBitmap parts.

In both cases (the adafruit logo and the QRCode) starts ok (as in the first top section of the bitmaps are printed fine), but then follows with garbled content.

I suspected a buffer overrun, so I added a setTimes statement to the example with 2X, and 3X the default values. There's speed difference in the printing, but no change in what is being printed.

Printer Firmware version: 2.68

• Arduino board: tried with Feather M0 and MKR1010

• Arduino IDE version: 1.8.19

• List the steps to reproduce the problem below (if possible attach a sketch or
  copy the sketch code in too):

Used example sketch A_printertest.

Unable to reproduce. Same board, same IDE, same printer firmware.
Please check:

• Adafruit SAMD Boards package version (current is 1.7.10)
• Power supply (5–9V suggested, 2A or better)

Thanks for checking! Will check again
