Like say if I just used the GR command and drew a low resolution picture with HLIN and VLIN, could I somehow send that to the printer? I first tried to use PR#1 as the first line of code, thinking that would send everything to the printer instead of the monitor, but that only sent the text I had below the graphics and not the picture itself.
Is there a relatively easy way to do this?

You don't need more hardware, but software.
Essentially, the ImageWriter is put into graphics mode, and the image can
then be read from the screen and printed.
I recall a program that I used; I think it might have been a Beagle
Brothers product.

Anthony

The Imagewriter will print graphics, but there's nothing in ROM that knows a
thing about doing so. You'd need to write your own screen-dump software, or
find someone else's. I had working Hi-Res screen-dump code that I'd written
back in the day, but I'm not sure if I still have it.

You wont be able to use HLIN or VLIN, as the printer can only print one dot at a time, but you could probably use PLOT. PLOT plots to the hi-res screen, so you will have to write a program that at the same time plotting to the screen, will send a plot to the printer. Although, I think plotting one pixel at a time defeats the purpose of printing a picture. Just PLOT or DRAW everything to the screen, then print the whole picture. Two hi-res pictures can be printed side by side on a 8 inch wide printer paper.
I have a collection of printer routines for both imagewriter (serial) and Epson compatibles (parallel printing) for printing the full hi-res screen.
For printing in Dbl hi-res (IIe or greater) there is a couple of Nibble programs on disk in Asimov. "Three Way Picture Printer and DublStuff" print full screen dbl hi-res in color.
Email me so I have something to reply to, I can send you a disk image of what I have.

At the moment, I don't have any way of transferring disk images to the Apple II. None of my modern computers have a serial port, so I guess I would need a serial to USB adapter.

The smallest program I have is small enough to type in but only prints in only one of the six colors, so I will post it here.
1 HOME : PRINT "PRINT ON RIGHT SIDE OF PAPER (Y/N) -> ";: GET A$:T = 40 * (A$ = "Y")
2 PRINT : PRINT "WHICH COLOR WOULD YOU LIKE TO PRINT IN:": FOR I = 0 TO 6: READ A$: HTAB 10: PRINT I" - "A$: NEXT : DATA BLACK,YELLOW,RED,BLUE,ORANGE,GREEN,PURPLE
4 PRINT : PRINT "CHOICE (0-6) -> ";: GET A$:C = VAL (A$)
5 PRINT CHR$ (21): CALL - 3100: POKE 230,32
10 D$ = CHR$ (4):E$ = CHR$ (27): PRINT D$"PR#1"
11 PRINT CHR$ (9)"80N"
12 PRINT E$"L000": IF T = 40 THEN PRINT E$"L040"
15 PRINT E$"T07": PRINT E$"K"C: PRINT E$"D" CHR$ (0) CHR$ (32)
20 FOR I = 39 TO 0 STEP - 1: POKE 6,I: FOR J = 0 TO 2: PRINT E$"G0192"
30 CALL 768: NEXT : PRINT : NEXT
40 PRINT : PRINT E$"T08": PRINT D$"PR#0"
50 TEXT : HOME
0300:A9 00 D0 04 A9 00 85 09 A9 40 85 08 A5 09 85 1B
0310:0A 0A 85 1A 0A 2A 2A 05 1A 29 1F 05 E6 48 29 00

I tried to type in your code tonight, but the computer gave me sytax errors on the lines at the bottom (what I'm guessing is assembly code, starting at 0300)
I wrote code to draw a simple picture on the screen with HLIN and VIN, and then typed in your code at the end of that. I don't know what I'm doing wrong.
BTW, Matthew, I'm definitely interested in getting a couple of color ribbons if/when I can ever figure this out!

Even without the CALL -151 you shouldn't get syntax errors.
The ML lines would just show up as applesoft line #300,310,320,330,340
Getting a SYNTAX ERROR baffles me as to what you might be entering.

Chris, what you're looking for is a screen dump program.
They dump a selected hi-res screen to your dot matrix printer. Practically
all of them are monochrome, and most don't do lo-res or double hi-res.
There were a lot of them in the 1980s, and several parallel printer cards
had the capability in ROM.
A search should turn up everything from type-in programs to commercial
ones. They were a common utility.

The Beagle Brothers program is called 'Triple Dump' and could dump any type of screen to the printer.
