printers to microcontroller

microcontroller printing

dear all
m designing a project in which i need to attach a small portable printer to the microcontroller to take the print out ... m new to this please help me out for how to proceed on this which type of printers are available.....

Hi quite simple task
EPSON is leader in this..........

You will have to decide Serial or Parallel? Impact, Thermal or inkjet?

You can also buy only mechanism and control it by your own hardware and program must be cheaper but little difficult.

Try to search mini printer on Google
for example **broken link removed**

Can anybody provide source code for printing serial output to printer

 

[bungee-]

Output differs from printer to printer. Usually goes like that:
1. Init printer (ESC codes, that setup printer font type, format of paper and some other details)
2. Send to the printer clear text .... with ESC formating
3. Send to printer to "spit out" the paper .... (again ESC command)

Specific printers have specific codes, so for detailed info you should specify printer type.

hello der!!can you help me to interface ftp628mcl103 thermal printer with 8051??

First thing to be understand is what type of printer used.
1.Laser printer
2.Inkjet printer
3. Normal (old printer)

second thing is if we used microcontroller than what type of interface you want
like
1. Serial communication (RS 232 Interface)
2. Parallel communication (Centronics Interface)
3. Parallel communicatin (GPIB)

After selecting this two thing than only possible to go ahead.

If you are using a serial printer, you should be able to connect directly to the S/O pin on your micro, no need to convert to rs232. You will just need this and a common ground connection to the printer, it should work at TTL levels. Unlikely you would need any handshaking, as printers usually have their own buffer. If you are using a high level language such as Basic or C, you can just use the normal print commands. Just make sure that you micro and printer is set to the same baud rate. This is by far the easiest way to connect a printer. Disadvantage is that most printers today are USB, you would probably be restricted to data logging matrix or thermal units, unless you can find an old printer somewhere. Parallel port connection is also doable, but rather more difficult.
