• Ubuntu 14.04:LTS , HPLIP loses USB connection to HP laserjet

  - by Gareth

  This is my first post, so please let me know if i have inadvertanly broken any rules. Problem There seems to be a problem with HPLIP and USB connections in ubuntu 14.04LTS. After upgrading i managed to get the printing to work but today it has broken. Initial Issue (Solved) After upgrading to unbutntu 14.04 LTS my printer lHP LaserJet 1018 stopped printing (code=12) Looking through the Forumsthere are several issues with printitng and HPLIP so I was able to troubleshoot this. The steps I took were : Reran HPdoctor Ran hp-check Un-installed and installed the latest version of HPLIP (3.14.4) Checked the USB connections lsusb and lsusb-v Re-ran hpcheck Removed the printer from HPLIP Re-ran hpcheck Manually configued HPLIP to the printer hp-setup-g <xxx:yyy> And this worked HPLIP was able to see the printer in the USB , test page printed and was happily working for a few weeks. Current Issue Printer Not working However today my wife complains the printer is not working and checking see that although HPLIP has the same error code and did not seem to be able to see the printer although running lsusb could see the printer. Initially thought this may be due to usb given a new bus/device after being turned on and off and went to repeat the steps above at the moment still seeing an error in that the HPLIP is complaining that it cannot see the device **error: Device not found. Please make sure your printer is properly connected and powered-on.** current Observations lsusb output ## Bus 002 Device 007: ID 03f0:4117 Hewlett-Packard LaserJet 1018 sudo hp-check output *> "duan@duan-Lenovo-B550:~$ sudo hp-check [sudo] password for duan: Saving output in log file: /home/duan/hp-check.log HP Linux Imaging and Printing System (ver. 3.14.4) Dependency/Version Check Utility ver. 15.1 Copyright (c) 2001-13 Hewlett-Packard Development Company, LP This software comes with ABSOLUTELY NO WARRANTY.

USB lead Works with the Windows 7 laptop Printer Works with windows 7 laptop Questions Is this a Bug with HPLIP or an issue with laptop/printer? Supplementary question if it is a bug what information is needed and where should it be sent ? Any suggestions on how to get the printer to work correctly with Ubuntu 14.04LTS/HPLIP 13.4.3 so that it stays working ?

• How to disable other touch gestures after adding another tap gesture to the view?

  - by Hudson Duan

  I have a view with some tables and buttons on it, and then I want to add a tap gesture to the entire view, but I only want that gesture recognizer to recognize taps. Ideally, I want to do something when the added gesture recognizer is tapped, then remove that gesture recognizer after so the other buttons and tables can be accessed. Basically a tap to dismiss functionality that replicates something like the facebook notifications window, tap outside to dismiss, but not interfere with the buttons outside of the notifications view. Can anybody help? My current code is: NotificationsWindow *customView = [[[NSBundle mainBundle]loadNibNamed:@"NotificationsWindow" owner:self options:nil]objectAtIndex:0]; customView.frame= CGRectMake(12, 12, customView.frame.size.width, customView.frame.size.height); UITapGestureRecognizer *recognizerForSubView = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapBehindAgain:)]; [recognizerForSubView setNumberOfTapsRequired:1]; recognizerForSubView.cancelsTouchesInView = NO; //So the user can still interact with controls in the modal view [customView addGestureRecognizer:recognizerForSubView]; [self.view addSubview:customView]; UITapGestureRecognizer *recognizerForSuperView = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapBehind:)]; [recognizerForSuperView setNumberOfTapsRequired:1]; recognizerForSuperView.cancelsTouchesInView = NO; //So the user can still interact with controls in the modal view [customView.superview addGestureRecognizer:recognizerForSuperView]; (void)handleTapBehind:(UITapGestureRecognizer *)sender { NSLog(@"tapped"); [[self.view.subviews lastObject] removeFromSuperview]; [self.view removeGestureRecognizer:sender]; } I want to make it so that the recognizer for the super view dismisses the subview, but not to interfere with the other taps on the super view.
