Star-Dust Expert Licensed User Longtime User Jun 2, 2022 #2 Hi Roger, You should indicate the error you are experiencing (copied in test format). It is also useful to know which printer you are testing it with, not all printers have the same method of printing images. Finally, are you using the DEMO version? Upvote 0

Star-Dust Expert Licensed User Longtime User Jun 2, 2022 #4 I would like to know which error it generates not which code. An error in the logs? is the error in the print? Upvote 0

As I wrote you I needed the errors in text format not in image format. The first time you sent me a piece of code and the second time two images. I don't know if it's my fault that I don't write English well, but it could be the other way around. Anyway, the error I see is that it is looking for a file named Logo.bmp. In my example there is no file with this name nor in the code that you have attached in a ZIP file. So you would like us to find an error on a different source than the one you gave us. It seems like an impossible operation. I would suggest a few things: First check why look for this image. Second I saw that you create the image from code, but it doesn't reflect the correct dimensions. The image I put in my code is 330pixel wide. this is the maximum he has to achieve. Third thing, always use the latest version of b4A. Finally there is an error that is not clear to me. It seems that you are looking for a method (LogImpl) which is not part of my library, I suppose something you added yourself. From the pictures I can only understand that. You didn't tell me what printer you use ..... maybe if you give me the information I ask (in text format) you could understand more Upvote 0

virpalacios Active Member Licensed User Longtime User Jun 2, 2022 #8 Hi, I got some problems in printing images (bitmap logo and qrcode). In some printers it worked fine but in other printers I got a extrage behavior (garbage printing). SD indicates it was a buffer issue, so I divided my printing and for each section I cleared buffer. Best Regards Upvote 0

R rogel a. tolentino Member Licensed User Longtime User Jun 3, 2022 #9 I'm glad to inform you that when I installed a new version of B4a your sample program run smoothly. but when i change this Printer.AddBuffer_Bitmap(LoadBitmap(File.DirAssets,"qr.jpg"),0) to Printer.AddBuffer_Bitmap(LoadBitmap(File.DirRootExternal ,"Logo.bmp"),0) error at my android phone with message "Bluetooth Printer Sample has stoped " considering that Logo.bmp exist at said location even I add this rp.CheckAndRequest(rp.PERMISSION_READ_EXTERNAL_STORAGE) rp.CheckAndRequest(rp.PERMISSION_WRITE_EXTERNAL_STORAGE) You have mentioned that this is a demo version. I am interested to a real one and willing to donate? How much should I donate? Please help me on how to print image and barcode. Thanks Upvote 0
