I am a sysadmin, and my computers run Debian Jessie. (I know, I'm working on updating soon.) When I try to print to a network printer, sometimes it works flawlessly. Other times, however, the program I'm printing from will gray out and the print dialog will take forever to come up. All the programs on the computer will hang. At times like these, running lpstat -t will hang as well. Furthermore, after a print job is completed, lpstat -t will show, indefinitely:




Printer printername is idle. Enabled since datetime.

Waiting for printer to finish.




The printer usually accepts more jobs anyway.



Restarting CUPS will usually temporarily fix all of these problems, but I have been unable to identify the source. What can I do to fix this?



Update:



Looking in my log files, I see cupsd is not idle any more, canceling shutdown over and over.

  • I can guess your network printer was not enough memory. How large file did you send to the network printer?You should check your network speed before you did network printing.

  • When you said this problem only began recently. You should check your network. Maybe your network got a problem recently too. Maybe Someone sent a large file to network printer. Did you change anything on CUPS and print server recently?

  • What does localhost:631 say? I think that web server is the most reliable interface to CUPS.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
