str_pad will result in a new line

[dpayet]

Hello,

I've tried the receipt-with-logo example and the lines are not aligned on right. It does a new line below the first. I have the item on the left and its price below the item (it should be on the right).

My printer is a Epson TM-T88IV. Is there any config to do to adjust the paper width or the print size (or something else ?) :)
Thanks (and sorry for my english).

You might just need to change some numbers. I wrote that example for a printer with 48 characters per line and your printer looks like it's narrower, maybe 42.

Look for $leftCols and $rightCols in the example.

class item
{
...
    public function __toString()
    {
        $rightCols = 10;
        $leftCols = 38;

        if ($this -> dollarSign) {
            $leftCols = $leftCols / 2 - $rightCols / 2;
        }
        $left = str_pad($this -> name, $leftCols) ;
        
        $sign = ($this -> dollarSign ? '$ ' : '');
        $right = str_pad($sign . $this -> price, $rightCols, ' ', STR_PAD_LEFT);
        return "$left$right\n";
    }
}

It is currently 38 + 10 (48 columns total), you need to make these numbers smaller, maybe start with 34 + 8 and decrease from there if the lines still wrap,

Shame on me, I should have seen this ...

Big thanks mike ! :)

I also notice that you have an "ñ" sign on your receipt. Since you are writing in French, I'm guessing you are trying to print a Euro.

If you upgrade to v2.0.1, you can use the CapabilityProfile called TM-T88IV which should correct this for your specific printer.

A sort of minimal example would be-

use Mike42\Escpos\CapabilityProfile;
use Mike42\Escpos\Printer;
use Mike42\Escpos\PrintConnectors\FilePrintConnector;

$profile = CapabilityProfile::load("TM-T88IV");
$connector = new FilePrintConnector("/dev/usb/lp0");
$printer = new Printer($connector, $profile);

$printer -> text("Article gratuit      € 0,00\n");

$printer -> cut();
$printer -> close();
