Unfortunately the following doesn't work because the informational output gets mixed with the PDF output. As you can see here Object w = etc
I have been doing a two step glabels-3-batch to LPR process but have made it so I don't have to write an intermediate file to disk.
Here is my approach in shell scripting
1 2 | cat merge.csv | glabels-3-batch -i - -o /dev/stdout template.glabels | \sed -n '/%PDF-1.5/,/%%EOF/p' | lpr -PPDF -J jobname |
And in PHP
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 | /** * Send job to gLabels * * Sends the completed template to the printer held in the $print_settings array * @param string $template full path to glabels template * @param array $printerDetails Printer Information * @return array Array holding the results of the lpr command */ public function glabelsBatchPrint(string $template, $printerDetails) { $this->setGlabelsTemplate($template); $this->setPdfOutFile(); // this is /dev/stdout // this writes the glabels csv data to disk // for testing $this->createTempFile($this->printContent); $cmdArgs = [ 'glabels-3-batch', '-o', $this->getPdfOutFile(), // use tempnam(TMP, glabels) to get a file name $this->getGlabelsTemplate(), ]; // when you have csv data your need to merge it into the template // from stdin eg. cat merge.csv | glabels-3-batch -i - -o outfile.pdf template.glabels if ($this->glabelsMergeCSV) { /** * add stdin ("-i -") to glabels command line when piping CSV data into glabels: * glabels-3-batch -i - -o * /var/www/wms/app/tmp/20190701182321-customPrint.pdf * /var/www/wms/app/webroot/files/templates/100x50custom.glabels */ array_splice($cmdArgs, 1, 0, ['-i', '-']); } // printContent is set elsewhere but contains // the merge csv data $results = $this->runProcess( implode(' ', $cmdArgs), $this->printContent ); // bug out if the glabel-3-batch process fails if ($results['return_value'] !== 0) { return $results; } // if successful pull the stdout which was returned from // glabels-3-batch and // extract the PDF from the stdout stream //$pdfPattern = '/(%PDF-1.5.*%%EOF)/s'; //preg_match($pdfPattern, $results['stdout'], $matches); /** * This grabs the PDF file out of the PDF */ //$this->setPrintContent($matches[0]); $this->setPrintContent(file_get_contents($this->getPdfOutFile())); unlink($this->getPdfOutFile()); return $this->sendPdfToLpr($printerDetails); } /** * send gLabels PDF to designated LPR printer * @param string $printer Print queue name * @return array Array with stdout stderr cmd and return_value */ public function sendPdfToLpr($printer) { $jobId = $this->getJobId(); $cmdArgs = [ 'lpr', '-P', $printer, '-#', $this->glabelPrintCopies, '-J', $jobId, '-T', $jobId, ]; $returnValue = $this->runProcess( implode(' ', $cmdArgs), $this->printContent ); // set back to 0 for next run $this->setPrintCopies(0); return $returnValue; } /** * run process * @param string $cmd Command line to run * @param array $printContent Not sure what this is * @return array array of stdin, out,err and exit code, cmd */ public function runProcess($cmd, $printContent) { // code... $descriptorspec = [ 0 => ['pipe', 'r'], // stdin 1 => ['pipe', 'w'], // stdout 2 => ['pipe', 'w'], // stderr ]; $pipes = []; $process = proc_open( $cmd, $descriptorspec, $pipes, $this->getCwd(), //cwd orig TMP null// env null = current ); // writing straight to stdin works fwrite($pipes[0], $printContent); fclose($pipes[0]); $stdout = stream_get_contents($pipes[1]); fclose($pipes[1]); $stderr = stream_get_contents($pipes[2]); fclose($pipes[2]); $return_value = proc_close($process); /* return an array with all the necessary information */ return compact('cmd', 'stdout', 'stderr', 'return_value'); } |
