I wrote an Epson driver to print bw graphics for the Epson matrix printers back in the late 80s. It worked well for me. I don't remember the details, but the code is small and easy to analyze.

@gerliczer: First I Iry to search the forum first. But these topic from umlaut , and specialized chars. not from the differences of char codes, and screen codes.
As I realized the char code solution is:
I checked the code tables again in my books, and it needs to add $40 if the value less than $1f
LDA $0c00
JSR converter
print a register
converter
CMP #$1F
BCS SKIP
CLC
ADC #$40
SKIP
RTS
@Crown:
If you found it, I can push to the next version of mouse extension. as a new feature (there is some empty space in the rom)

Precursor to the my original graphic converter, I had a few routines for printing graphics, both hires and multicolor. I don't see it available here, hopefully it will be on one of my disks or tapes.

Click the "Search" link at the top, type or copy-paste "hardcopy" without the quotation marks, click the "search" button or press enter, pick and choose to your heart's content in the results.

| Rutins in assembly
Hi!
I would like a topic for assembly questions.
- First:
I would like a routine to print the entire screen.
I wrote the most of it. My problem is how I convert the screen codes to the printer format?
As I think, these are the ascii chars.
Is there any finalished routine that I can use for it?
"a" screen: $01 ascii: $41
"0" screen: $30 ascii: $30
as I think, it is not just an add $40
- Second question will be the graphical.. :) maybe..
