Fixes issue #46.

Important note: This change breaks 5 tests. So please double check if all of these model outputs should be changed, or if previous implementation for some of them was correct.

Changes output of:

• __tests__/resources/cmp-20_qrcode.bin
• __tests__/resources/dr800_draw_buffer.bin
• __tests__/resources/mp-4200_th_draw_buffer.bin
• __tests__/resources/mp-4200_th_draw_file.bin
• __tests__/resources/printid_qrcode.bin

It this is correct, I will update all these files for all tests passing (by additional commit). Should be done before PR approval. In other cases, further discussion is needed. :-)

Thanks for this pull request fix, i will test on printer this new binaries, but its problably that this image printing will get spacing between two lines for model MP-4200 TH, i will put the results here

Thanks for the answer @mazinsw. I am interested in testing your model.
I found the specifications of your MP-4200 TH.

There is the interesting message on page 34:

A full print line with ‘N’ columns will need N*3 bytes. If the image to print has less than ‘N’ graphic
columns, a LF command must be sent to perform line printing. Text and graphic may be mixed
in the same line.

So for a smaller image, it looks like the 0x0A is correct. But for sure we can also test if a behavior is the same on images with the exact maximum width.

@samueldurantes or @grandchef - Should I close this PR? It is already reviewed, and approved, but nobody merged it.

[samueldurantes]

@mazinsw can I merge this PR?

I have not tested yet (sorry i forgot), i remember that this line break and create a horizontal spacing between image lines on some of these affected printers, if you can test and merge, do it, because i'am out of this repo/company
