Sending a print job but the page is blank

[dustin-auby]

Hi,

I am trying to send a print job with this library but the page comes out blank. the printer im testing with doesnt support pdf but does support image/jpeg . the printer receives the job and starts printing but then nothing is on the page. Any assistance on this would be greatly appreciated.

This is the code im using to send the job
var transport = HttpIppClientTransport(true) val uri = URI.create("ipps://8C2279000000.local:631/ipp/print") println("Print job sent to $uri") val printRequest = IppPacket.printJob(uri) .putOperationAttributes(documentFormat.of("image/jpeg")) .build() transport.sendData(uri, IppPacketData(printRequest, FileInputStream(filePath)))

These are the printer attributes. i did not get them from this library but im sure they are the same

oh i forgot to mention when i send the same file through ios it works fine

[psoreide]

Try using 'documentFormat.of("application/octet-stream")' which is telling the printer to auto-detect. I have experienced some printers only accept that document format.

[dustin-auby]

il test again but i have already tried this. thanks

[dustin-auby]

Ok tested with

var transport = HttpIppClientTransport(true) val uri = URI.create("ipps://8C2279000000.local:631/ipp/print") println("Print job sent to $uri") val printRequest = IppPacket.printJob(uri) .putOperationAttributes(documentFormat.of("application/octet-stream")) .build() transport.sendData(uri, IppPacketData(printRequest, FileInputStream(filePath)))

Same issue blank page

Ok tried on a seccond printer and still not luck. This printer is a brother printer. again i can print from ios but not android

@dustin-auby What is the mimetype of file being sent via sendData ? is it a pdf file or jpeg file?

Since the printer does not support application/pdf document format, it cannot handle the pdf file. Even though the print job request is valid, so a job is created but the print is not able to handle data received via the sendData request hence the blank page.

The printer would require the client to render the pdf into a supported format like PWG raster and send it to printer via a send-document operation.

I have tried sending Jpeg (image/jpeg) with a jpg image, application/octet-stream with a jpg,png and pdf and i have now also tried PWG raster . none of them work on either printer.

i have also tried the sample scripts for print and render and get the same results. surely one of those formats would work on at least one printer ?

Hi @dustin-auby Are you getting any IPP error code as part of the printer response? Can you try like below and check and provide the request and response packets?

I am using the code below and haven't encountered any issues when testing it with some HP printers.

@Test
fun documentFormatTest() {
    val transport = HttpIppClientTransport(true)
    val uri = URI.create("ipps://192.168.5.38:443/ipp/print")
    println("Print job sent to $uri")
    val printRequest = IppPacket.printJob(uri)
        .putOperationAttributes(Types.documentFormat.of("image/jpeg"))  // or "application/octet-stream" also works
        .build()
    val path = javaClass.classLoader.getResource("sample.jpg")?.path ?: Assert.fail("Resource not found")
    println(path)
    println("Sending ${printRequest.prettyPrint(100, "  ")}")

    val response = transport.sendData(uri, IppPacketData(printRequest, FileInputStream(path as String)))
    println("Received: ${response.packet.prettyPrint(100, "  ")}")
}

the printer targeted above supports the below attributes for document-format

document-format-default = "application/octet-stream" (mimeMediaType),
document-format-supported = [
  "application/vnd.hp-PCL" (mimeMediaType),
  "image/jpeg" (mimeMediaType),
  "application/PCLm" (mimeMediaType),
  "image/urf" (mimeMediaType),
  "image/pwg-raster" (mimeMediaType),
  "application/octet-stream" (mimeMediaType) ],

You can also try not putting any operation attributes because in that case printer suppose to use the default which is "application/octet-stream" , same as in your printer as well.
so like val printRequest = IppPacket.printJob(uri).build();

"image/jpeg" or "application/octet-stream" should work directly, like this code, but for PCLm or pwg-raster we need to render and generate separate pclm or pwg streams.
