# Plotter information

## Sony PRN-C41(D) / General PCP-5501 / Toshiba HX-P570
This information is copied from the original Sony manual and some parts are from the Creative Greetings software manual. The Sony plotter was release with Plotter (Creative Greetings) software. Also some add on graphics are released for this software, see also: https://www.generation-msx.nl/group/sony-plotter-series/97/

### PRN-C41 27C32 ROM contents

The dumped European ROM is a 4 KiB 27C32 EPROM.
The byte layout matches a plotter vector-font ROM:

| Address range | Contents |
|---|---|
| `$0000-$000f` | Small unidentified header / lookup constants. |
| `$0010-$010f` | 256-byte monotonic lookup table with values `$02-$0f`; likely scale, spacing, acceleration, or vector timing related. |
| `$0110-$020f` | 256-entry glyph offset table. Each byte is the low byte of a glyph record address; the high byte increments whenever the offsets wrap. |
| `$0210-$0f9e` | 256 variable-length glyph/vector records, aligned with MSX character codes. Each record ends in a command byte with bit 7 set. |
| `$0f9f-$0fff` | Erased/unused EPROM padding (`$ff`). |


The glyph records use chain-code vector commands. Bit 7 marks the final command
byte in a glyph record. In the lower 7 bits, bits 6..4 encode vector length as
`value + 1`, bit 3 is the pen state (`0` = move, `1` = draw), and bits 2..0
select one of eight compass directions. For manual-oriented rendering the ROM
X axis must be mirrored: direction code `0` is north, `1` appears north-east,
..., and `7` appears north-west on the rendered sheet. The records line up with
the plotter character codes, so `$20` is space and `$41` is `A`. Glyphs
`$00-$1f` are present too; these are the alternate characters printed with
`CHR$(1)` followed by `$40-$5f` as shown in the service-manual character table.
For example, glyph `A` uses pen-up move commands (`02`, `10`, `13`) and visible
draw commands (`38`, `19`, `1B`, `3C`, `3E`); after the X-axis mirror used for
rendering, the `3E` crossbar is a 7-step westward draw that visually stops at
the vertical stroke.

### Dip Switches
The printer has four dip switches, which are by factory default all off.

Switch 1 and 2 are not connected at all according to the service manual.

Switch 3 is only connected on the Japanese model and selects between JIS and SHIFT-JIS. It is short circuited on non-Japanese models (so GND is on the pin to the chip that makes the selection).

Switch 4 is called CR/CR,LF. It selects the function of the carriage return code (ODH) in the plotter printer text mode. When it is set to:
- ON: the pen position is set to the beginning of the next line.
- OFF: the pen position is set to the beginning of the line.

You may have to set the DIP switches according to your software. Refer to the operating instructions of the software.

### Buttons
The printer has 4 buttons:

| Button | Function |
|---|---|
| Reset | Press to reset the plotter printer into the power on status. This button is useful to reset the plotter printer when the printing operation is interrupted. Refer to the software's manual for how to interrupt the printing operation. |
| Change Color | Press this button to turn the pen holder and change the printed out characters color. |
| Feed | Press this button to feed the paper. |
| Feed Back | Press this button to feed the paper back. |

### F command rotation bounds test
Exercises the F (new line) command in each rotation (Q0..Q3). Each rotation
starts near the "far" edge of its feed direction and then fires `P B` + `F`
in a loop to push the pen toward the opposite edge. With correct bounds
handling the glyphs pile up at the paper edge; without it they walk off
the paper.

Expected edges: rot 1 clamps at X=0, rot 2 at Y=30, rot 3 at X=960; rot 0
still flushes to a new page.

## Daewoo DPL-400 / Talent DPL-400 (not emulated yet)
The command set is almost the same as the Sony PRN-C41(D), but there are some differences. The manual is available, but there is no software that supports this plotter.

No documentation is available for this plotter at the moment. National did release some software for this plotter, but without the manual it is hard to say how it works.

77	### PRN-C41 27C32 ROM contents
78
79	The dumped European ROM is a 4 KiB 27C32 EPROM.
80	The byte layout matches a plotter vector-font ROM:
81
82	\| Address range \| Contents \|
83	\|---\|---\|
84	\| `$0000-$000f` \| Small unidentified header / lookup constants. \|
85	\| `$0010-$010f` \| 256-byte monotonic lookup table with values `$02-$0f`; likely scale, spacing, acceleration, or vector timing related. \|
86	\| `$0110-$020f` \| 256-entry glyph offset table. Each byte is the low byte of a glyph record address; the high byte increments whenever the offsets wrap. \|
87	\| `$0210-$0f9e` \| 256 variable-length glyph/vector records, aligned with MSX character codes. Each record ends in a command byte with bit 7 set. \|
88	\| `$0f9f-$0fff` \| Erased/unused EPROM padding (`$ff`). \|
89
90
91	The glyph records use chain-code vector commands. Bit 7 marks the final command
92	byte in a glyph record. In the lower 7 bits, bits 6..4 encode vector length as
93	`value + 1`, bit 3 is the pen state (`0` = move, `1` = draw), and bits 2..0
94	select one of eight compass directions. For manual-oriented rendering the ROM
95	X axis must be mirrored: direction code `0` is north, `1` appears north-east,
96	..., and `7` appears north-west on the rendered sheet. The records line up with
97	the plotter character codes, so `$20` is space and `$41` is `A`. Glyphs
98	`$00-$1f` are present too; these are the alternate characters printed with
99	`CHR$(1)` followed by `$40-$5f` as shown in the service-manual character table.
100	For example, glyph `A` uses pen-up move commands (`02`, `10`, `13`) and visible
101	draw commands (`38`, `19`, `1B`, `3C`, `3E`); after the X-axis mirror used for
102	rendering, the `3E` crossbar is a 7-step westward draw that visually stops at
103	the vertical stroke.
104
105	### Dip Switches
106	The printer has four dip switches, which are by factory default all off.
107
108	Switch 1 and 2 are not connected at all according to the service manual.
109
110	Switch 3 is only connected on the Japanese model and selects between JIS and SHIFT-JIS. It is short circuited on non-Japanese models (so GND is on the pin to the chip that makes the selection).
111
112	Switch 4 is called CR/CR,LF. It selects the function of the carriage return code (ODH) in the plotter printer text mode. When it is set to:
113	- ON: the pen position is set to the beginning of the next line.
114	- OFF: the pen position is set to the beginning of the line.
115
116	You may have to set the DIP switches according to your software. Refer to the operating instructions of the software.
117
118	### Buttons
119	The printer has 4 buttons:
120
121	\| Button \| Function \|
122	\|---\|---\|
123	\| Reset \| Press to reset the plotter printer into the power on status. This button is useful to reset the plotter printer when the printing operation is interrupted. Refer to the software's manual for how to interrupt the printing operation. \|
124	\| Change Color \| Press this button to turn the pen holder and change the printed out characters color. \|
125	\| Feed \| Press this button to feed the paper. \|
126	\| Feed Back \| Press this button to feed the paper back. \|
