Is there any idea or solution that I can do, please let me know. Thank you in advance.

Hi,

I think the easiest way would be just to resize the image before printing.

[kechankrisna]

Thank you for your response, I did resize to fit the page by just 272 pixel, but it seems like all printing image just take only half of the paper width. I also did resize to make it to be bigger, but got the same result.

[kechankrisna]

But when I change highDensityHorizontal to true and highDensityVertical to true in printImage() method, I get full width printing, but another issue has happened, which is the texts printed are not clear, it was a bit bold and dark.

[andrey-ushakov]

So any image takes exactly a half of the width? I would say it should depend on image width/height ratio but unfortunately I can't test it as I don't have a POS printer right now... There are chances that it also depends on a printer's brand.

For the unclear printing with highDensity = true, did you try to print a high-resolution image? Does it resolve the issue?

[kechankrisna]

Yes, I did test it by using the same image I printed with browser. but the quality of image I printed using browser is better quality than. It is cleared text.

[kechankrisna]

Here the result of what I tested with image captured with width of 270px. https://ibb.co/NF6yCZf

It took only haft of the paper page to print.

Hi bro@kechankrisna

Could you help share the printer model details?
Thank in advance

Hi @kechankrisna

I finally have time and a pos printer to test the issue you have described.
If you can share your image and the exact code, I can test it on my device and fix the problem.
As far I can see from your image, you are using a 160mm paper and this lib was developed for a 80mm printer. Probably the easiest way (but definitely not the best) is to add a parameter in future releases to define the paper size.

[kechankrisna]

I am sorry for being late to reply on this problem, I found the solution now, by change picture width to 570px while I also changed highDensityHorizontal to true and highDensityVertical to true for printImage() function. My printer model is X-Printer xp-n160ii printer.

try to print as image bro

[ul-rotha]

how to write receipt as image bro?

[kechankrisna]

you can use any plugin to capture widget to image. This package can be found in pub or I created one too.

image so small after capture screen and pass to ticket.image(image);

[kechankrisna]

change picture width to 570px so that would be enough

[ul-rotha]

could you link url code for changing picture width? i could not found

[kechankrisna]

Here is a sample:
final Ticket ticket = Ticket(PaperSize.mm58); final Image image = decodeImage(file.readAsBytesSync()); final Image thumbnail = copyResize(image, width: 572); ticket.image(thumbnail);
