Printing At Night

“If the Print & Fax lock icon appears locked, click the lock icon and enter an administrator name and password when prompted.”

I haven’t touched a Mac in over a decade but one came to my home yesterday in the hands of a visitor. A party was being planned and a document was produced on the Mac. It should have been simple to print over my LAN. I allow all comers. Somehow, it didn’t work. The printer was seen but no driver could be found and there was the “locked” icon beside it. The last time I was in a school that used Mac OS (Pre UNIXy version) printing kept failing to a bog standard HP Laserjet printer so the Macs e-mailed a Mac which had been liberated by me to GNU/Linux. A tech arrived eventually and made the Macs print again but within an hour of his departure printing failed again. Besides connectivity, the Macs butchered every file with a MacOS header of some kind which I had to strip off… MacOS/X is apparently much more sane.

The owner had never printed and I didn’t want to figure out MacOS. I knew that it had a UNIX connection so I asked the visitor to “open a terminal”. The result was a blank stare. So, I rephrased the question to “Where do you find your applications?”. Voila! A terminal window was opened. We tried FTP but the visitor could login with “anonymous” credentials but could not do a “put” (forgot to cd to pub… / is not writable…). Then we used SCP and moved the files to Beast and I printed them from there. The files came from PS in PDF and there was no problem printing from GNU/Linux once the files had moved. Aren’t flexibility and open standards wonderful?

I’ll stick with GNU/Linux. Apple makes no version for ARM so far and I do know how to get GNU/Linux to do anything.

PS: I checked why FTP had failed. It was user-error. We had not cd pub.

That was my mistake. So we had multiple solutions and two of them should have worked.
