Raw Printing in printnode increases the size of the content by 33% approx

[vasudharsai]

I'm printing 4x1 labels and trying both raw_uri and raw_base64 and that prints out the label with size of the content increased by 33% approx. Below is how I'm creating PrintJob

my_printjob_info = PrintNode::PrintJob.new(printer_id, 'PrintJob_OE4', 'raw_base64','InventorySticker_363467.txt', 'PrintNode-OE4') #using raw_base_64

my_printjob_info = PrintNode::PrintJob.new(printer_id.to_i, 'PrintJob_OE4', 'raw_uri',uri, 'PrintNode-OE4') # uri is the url in my application through which the file could be downloaded.

Please advice. Thanks

Hi Vasudharsai, If printing RAW documents the content is sent directly to the printer. Normal printing options like "fit to page" or "page size" generally don't have a effect. To increase the size of your content you'll want to have a look at how to do that in the RAW printing language you are using. I'm afraid PrintNode can't help with the content creation side of the printing process. Thanks, Peter

Not sure we are talking about the same thing but for base64 : the ratio of output bytes to input bytes is 4:3 (33% overhead). So that would be completely normal. Cf https://en.wikipedia.org/wiki/Base64

Sorry Vasudharsai I misunderstood your question. Quentin's reply is both accurate and a lot more helpful. Base64 encoding is used so that arbitrary binary data can be safely encoded in a JSON HTTP request body. This does make the API request to POST /printjobs more inefficient from a bandwidth point of view but these inefficiencies stop there. When the client software downloads any content it downloads a base64 decoded version without any base64 encoding overhead.
