----------------------- SUMMARY: Ubuntu version 16.04 and 18.04 Problem is reproducable by the bug reporter. Printer is HP Officejet Pro X476dw MFP. Notes: Printing documents with Hebrew fonts results in low quality with fuzzy lines (default CUPS converts the print job to a 300dpi PS before giving it to the hp driver) Expected behaviour: documents print at 600 dpi Actual behaviour: documents are printing at 300 dpi Additional notes: Bug reporter is in Ubuntu 16.04 but has checked the latest PPD file (v3.18.7) and issue still exists. “The PPD does not define the DefaultResolution parameter which causes CUPS to use a default of 300dpi.” Solution: Add to the PPD for this printer: the DefaultResolution parameter. For example: *DefaultResolution: 600x600dpi ----------------------- ** Changed in: hplip Status: Incomplete => New ** Changed in: hplip (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1385055 Title: HP Officejet Pro X476dw MFP prints in 300dpi To manage notifications about this bug go to: https://bugs.launchpad.net/hplip/+bug/1385055/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
