Print-Scaling Unknown Attribute

[cah-brandon-trebbien]

Getting the below error submitting a print request.

/home/vcap/app/node_modules/ipp/lib/serializer.js:73
if(!groupName) throw "Unknown attribute: " + name;
^
Unknown attribute: print-scaling

If I remove the attribute, print succeeds but is not scaling to fit the page. I see print-scaling is listed under the supported attributes in the serializer so not sure what is causing the issue. Here is the request being submitted:

fs.readFile('/path/to/file', (err, pdf) => {
if (err) throw err;
var msg = {
"operation-attributes-tag": {
"requesting-user-name": "Name",
"job-name": "MyTestJob",
"document-format": "application/pdf"
},
"job-attributes-tag": {
"sides": "one-sided",
"finishings": "staple",
"print-scaling": "fit"
},
data: pdf
};
printer.execute("Print-Job", msg, function(err, res){
console.log(res);
});

Looks like this option got added in the one of the pull requests from last month. #77

Can the latest master branch be pushed to npm?

When I do npm install building from latest copy of master I am now getting the below:

The spec is not clear on how to handle tag 16: print-scaling=undefined. Please open a github issue to help find a solution!

Print scaling is an invalid attribute, but you can add the media attribute to specify the paper size. Although this attribute has a default value, it seems that this package did not pass in this default value by default, resulting in incomplete display during printing

const printJob = {
'operation-attributes-tag': {
'attributes-charset': 'utf-8',
'requesting-user-name': 'User',
'job-name': 'Print-Job',
'document-format': 'application/pdf'
},
'job-attributes-tag': {
media: 'iso_a4_210x297mm'
},
data: buffer
}

Perfect solution to size issues during printing!
