My laptop is not connected to a printer either. I can wander in and change the USB cable from the desktop to the laptop but I'm lazy. Generally I just save stuff to a thumb (jump) drive and shove that in the desktop machine to print.
There are a handful of MSPs that have no save function--the one that makes me craziest is Service Intelligence with that. The one Sinclair job I have done through their new website was a problem because they wanted a substantial narrative but didn't indicate maximum size. I did about an 8000 character narrative (in Word) which, when pasted into the form blew up the form because it could only handle 7000 characters. Luckily I could use the back button to go back and copy and paste the report into Word so I wasn't completely reinventing the thing.
Routinely I will hit "Select All" and "Copy" to get material from pdf files or other files where I can't just highlight and copy. Once the stuff is on the clipboard I can paste it into a Word document to save
