You need to adjust the -w parameter to the width of your own printer (mine is obviously 32 characters wide). I have called mine “thermof” (thermoFormated):įmt -cu -w32 –goal 30 | unix2dos | iconv -c -f UTF-8 -t 437 > /dev/usb/lp0įmt will eliminate line wraps which don’t match with your printer width and add new ones at the correct positions. You might also want to reformat a text file to match the short lines of the printer. You might want to create a “thermotest” script without -c and actual printer output to make sure all characters can be printed before you attempt to print. The -c option makes sure that characters which can’t be printed are ignored rather than cause an error and stop. Iconv simply translates UTF8 into the common printer default codepage 437.

Unix2dos makes sure the printer receives CR+LF at every new line. Then press “Enter” and “Strg+d” to stop editing and start printing.

Now you can just copy your text and then type “thermo” into a console and press “Shift+Ins” and/or type whatever you want to print. I named my script “thermo” and deposited it into /usr/bin. Unix2dos | iconv -c -f UTF-8 -t 437 > /dev/usb/lp0 You can create a simple script to be able to print TXT files or dump text to the printer using copy&paste: This would be sent to the printer by loading it from the web, or running the script on the command-line: php foo2.php $printer -> setJustification(Printer::JUSTIFY_CENTER) $printer -> text("Receipt for whatever\n") The above example would be written using escpos-php as: setEmphasis(true) The codes are quite tricky to work with manually, which is why I put together the escpos-php driver.

run lsusb -v and usb-devices (look for driver=)Īs a duplicated section from my earlier post, the printer uses ESC/POS, which means it accepts plaintext with some special commands for formatting.Ī simple receipt-generator, foo.php, might look like this: /dev/usb/lp1 Scaling this up.

Install a different linux-image if the driver is not on your computer at all.

If these steps don’t work, then your computer ether doesn’t have, or isn’t using usblp You’ll need to check a few things: Now log out and back in, and the previous test should now be working: echo "Hello" > /dev/usb/lp1 Troubleshooting: Check usblp If you plan to build a web-based point-of-sale system with this, then also add the www-data user to that group. If your username was bob, you would add yourself to this group using: sudo usermod -a -G lp bob This file is owned by group lp (“line printer”).
