The differences between the not-working PPD which you have attached and the working hpcups PPD you can see below.
Try to return to your original PPD via lpadmin -p PSC-750 -E -P PSC-750.ppd Does it stop working now? If so, apply each change show below manually to your /etc/cups/ppd/PSC-750.ppd and do not forget to restart CUPS after each change. Tell which change actually makes the printer working again.\ ---------- --- PSC-750.ppd 2009-08-27 01:33:02.000000000 +0200 +++ x 2009-08-28 13:38:51.000000000 +0200 @@ -1,6 +1,6 @@ *PPD-Adobe: "4.3" -*% PPD file for HP PSC 750 with CUPS. -*% Created by the CUPS PPD Compiler v1.2.3. +*%%%% PPD file for HP PSC 750 with CUPS. +*%%%% Created by the CUPS PPD Compiler CUPS v1.4.0. *% (c) 2008 Copyright Hewlett-Packard Development Company, LP *FormatVersion: "4.3" *FileVersion: "hpcups 3.9.8" @@ -12,10 +12,7 @@ *ModelName: "HP PSC 750" *ShortNickName: "HP PSC 750" *NickName: "HP PSC 750, hpcups 3.9.8" -*PSVersion: "(3010.000) 705" -*PSVersion: "(3010.000) 707" -*PSVersion: "(3010.000) 815" -*PSVersion: "(3010.000) 853" +*PSVersion: "(3010.000) 0" *LanguageLevel: "3" *ColorDevice: True *DefaultColorSpace: RGB @@ -29,10 +26,11 @@ *cupsFlipDuplex: True *cupsModelName: "DESKJET 930" *1284DeviceID: "MFG:HP;MDL:psc 750;DES:psc 750;" -*cupsVersion: 1.3 +*cupsVersion: 1.4 *cupsModelNumber: 0 *cupsManualCopies: True *cupsFilter: "application/vnd.cups-raster 0 hpcups" +*cupsLanguages: "en" *UIConstraints: *Duplex *OptionDuplex False *UIConstraints: *OptionDuplex False *Duplex *UIConstraints: *hpInkSet Color *OutputMode NormalGray @@ -280,7 +278,6 @@ *ParamCustomPageSize WidthOffset: 3 points 0 0 *ParamCustomPageSize HeightOffset: 4 points 0 0 *ParamCustomPageSize Orientation: 5 int 0 0 -*RequiresPageRegion All: True *OpenUI *Duplex/Double-Sided Printing: PickOne *OrderDependency: 10.0 PageSetup *Duplex *DefaultDuplex: None @@ -369,4 +366,4 @@ *Font Times-Roman: Standard "(1.05)" Standard ROM *Font ZapfChancery-MediumItalic: Standard "(1.05)" Standard ROM *Font ZapfDingbats: Special "(001.005)" Special ROM -*% End of hp-psc_750.ppd, 23766 bytes. +*% End of hp-psc_750.ppd, 23679 bytes. -- karmic printing regression on HP PSC 750 https://bugs.launchpad.net/bugs/394447 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
