Phomemo M220 compatibility

[bleriotx]

Code changes required to get Cups printer filter to work with M220 printer.

• Removed unneeded printer init codes.
• Modified the rendering code to send the print job in one sequence.

Please remove the code that is unused rather than to comment it out.
Don't add "2023-07-12 bleriotx - Fix for Phomemo M220 printer." in your comment the timestamp and the author are already given by the git log (with "git blame"), and you can put "Fix for Phomemo M220 printer" as the commit message header.

Did you test that this change doesn't break others printers support?

[bleriotx]

Sorry - I am new to all this and do not know the tools or the rules. This is why I was reluctant to get involved.
I have tested this on an M220, but do not own an M02 or M110 so cannot determine if it breaks them.

Probably better if somebody else reviews my findings in Issue #8 and determines if my changes are worthy.

OK! I will review and test it on M110 !

[daig0rian]

I have tested this pull request code and confirmed that it works on the M110 fine.


It is expected to work on M120 as well.

The main point of this pull request is to make the bitstream output by the CUPS driver closer to that of the official Windows driver released by Phomemo. This will solve issue #13 and also make this CUPS driver more compatible with the other Mxxx series.

The M110 and M220 can output images with more than 255 lines in a single BLOCK MARKER (i.e. GS v 0 command) without any problem. As far as I can tell, the M110 can output a 2398 line (=30cm) image in single BLOCK MARKER, and alsog the M110 and M220 Windows drivers only have single BLOCK MARKER, even for long label output.

Please merge the 3 commits in 1.
(you can use "git rebase -i HEAD~3" and then replace the 2 last "pick" by "fixup")

Closing the pull request as I don't know if it is relevant anymore.
