Merge lp:~philpem/ubuntu/utopic/ptouch-driver/ptouch-driver-fixup into lp:ubuntu/utopic/ptouch-driver

[Phil Pemberton]

Following up from discussion at https://code.launchpad.net/~philpem/ubuntu/utopic/ptouch-driver/fix-for-1342979/+merge/255190

This patch fixes a number of issues with the ptouch-driver printer driver:

  * Update the driver to use current CUPS APIs (not the older deprecated ones)
    and fix some compile-time warnings
  * Use the PPD API to get the value of the MediaType flag, which is used to
    pass the "Roll-fed media" flag into the driver
  * Correct the margins for QL-series P-Touch paper-label printers - these
    have a fixed 3mm margin (see the command spec) while the PT-series
    laminated plastic label printers have no appreciable margins.
  * Correct the format of the "ESC i z" (Print Information) command to match
    what is specified in the P-touch 500 raster command spec. Notably set the
    "passed parameter valid" bits, and send valid values for die-cut labels
    and continuous paper rolls.
  * Send the "ESC i d" (Set Margin) command for QL series printers. This is
    required by the command spec. The margin is set to 3mm for continuous
    paper and zero for die-cut (see the command spec)
  * Fix an issue with margins in the driver (disable blank-line padding). This
    was partly responsible for the "excess paper feed" issue.
  * Suppress the spurious "ESC i z" which was sent with incorrect contents at
    the start of the job.
  * Fix the Enable Cutter command.
  * Send 350 bytes of NULL/no-op commands at the start of the job. This allows
    the driver to recover the printer into a known state if communication was
    interrupted mid-transfer. This is recommended in the command spec.
  * Remove the "determined by page size" option from "Roll-fed media" as this
    no longer works.
  * Remove the "Advance Media" option, as this allowed users to configure the
    driver to generate print control codes which are illegal per the Brother
    documentation. This is now fixed at "Advance at end of job" (send a Form
    Feed at the end of every page, except the last which has an Eject
    command instead).
  * Merge in the changes formerly provided by send-esc-i-A-for-QL-only.patch.

[Till Kamppeter (till-kamppeter)]

Generally it looks OK, but we need to consider the following:

1. GIT repositories of a package (or any changes on it) should be done always with the quilt patches not applied and without .pc directory, to avoid redundancies and to make it easy to modify a patch without needing to modify a whole bunch of other files along with it.

2. Such a lot of changes should go upstream and not kept as distro patches to the eternity. If the upstream maintainer has disappeared, I suggest that you overtake upstream maintainership.

[Till Kamppeter (till-kamppeter)]

More remarks:

- You need to update the debian/changelog file. It should mention what you actually have changed/fixed. It seems to be unchanged from your previous merge proposal.

- 80 % of your patch are changes in the .pc directory and so redundant. also every change in your new patches appears a second time as change in the upstream source code. Please first clone the original GIT of the current package, "quilt pop -a", remove or exclude .pc/ and then recommit, after that do your changes and commit under the same conditions (patches unapplied and no .pc/ directory), propose the resulting repo for merge then.

[Till Kamppeter (till-kamppeter)]

I ave accepted your changes by replacing debian/patches/send-esc-i-A-for-QL-only.patch by your debian/patches/philpem-ptouch-fixes in the Ubuntu package and adding the description of your patch to debian/changelog. The resulting package I have uploaded as ptouch-driver 1.3-8ubuntu1 to Vivid. This should make up exactly the same package as your merge proposal. So I am closing this thread.

Thanks a lot for all the fixes. Make sure they get upstream as I told you earlier.

review: Approve

[Phil Pemberton (philpem)]

Thanks, Till!

The upstream developer is no longer maintaining the driver -- he says he no longer has time, which is fair enough. So I guess my Mercurial repository is the "latest" at the moment, and probably counts as a fork. I'll maintain it for my own use, but I don't intend to go any further with it. I certainly don't intend to, say, start buying P-touch printers and add support for them. I guess what I'm trying to say is, at the moment, it's good enough for me.

As for cloning the current Git repo - this version was done from the version in Bazaar, which may have had the existing patches already applied. Though that was after I'd run a build... perhaps I was misinterpreting what I saw. In any case, point noted. Committing patched source files did seem weird to me.

It'd be nice to see this fix make it into Utopic too (I guess that would be a backport?), though if that's not possible I'll probably take the package from Vivid and build it in a PPA for my own use.

+/** @file
+ * This filter processes CUPS raster data, converting it into a byte
+ * stream on stdout suitable for sending directly to a label printer
+ * of the Brother P-touch family.
+ *
+ * @version 1.2
+ * @author  Arne John Glenstrup <[e-mail]>
+ * @date    2006
+
+ * <h2>Invocation</h2>
+ * The filter is invoked thus:
+ *
+ *         rastertoptch job user title copies options [filename]
+ *
+ * @param printer  The name of the printer queue (ignored)
+ * @param job      The numeric job ID (ignored)
+ * @param user     The string from the originating-user-name (ignored)
+ * @param title    The string from the job-name attribute (ignored)
+ * @param copies   The number of copies to be printed (ignored)
+ * @param options  String representations of the job template
+ *                 parameters, separated by spaces. Boolean attributes
+ *                 are provided as "name" for true values and "noname"
+ *                 for false values. All other attributes are provided
+ *                 as "name=value" for single-valued attributes and
+ *                 "name=value1,value2,...,valueN" for set attributes
+ * @param filename The request file (if omitted, read from stdin)
+ *
+ * Available options (default values in [brackets]):
+ *
+ * @param PixelXfer=ULP|RLE|BIP  Use uncompressed line printing (ULP),
+ *                               run-length encoding (RLE) or bit
+ *                               image printing (BIP) when emitting
+ *                               pixel data [ULP]
+ * @param PrintQuality=High|Fast Use high quality or fast printing [High]
+ * @param HalfCut                Perform half-cut (crack & peel) when
+ *                               cutting [noHalfCut]
+ * @param BytesPerLine=N         Emit N bytes per line [90]
+ * @param Align=Right|Center     Pixel data alignment on tape [Right]
+ * @param PrintDensity=1|...|5   Print density level: 1=light, 5=dark
+ * @param ConcatPages            Output all pages in one page [noConcatPages]
+ * @param RLEMemMax              Maximum memory used for RLE buffer [1000000]
+ * @param SoftwareMirror         Make the filter mirror pixel data
+ *                               if MirrorPrint is requested [noSoftwareMirror]
+ * @param LabelPreamble          Emit preamble containing print quality,
+ *                               roll/label type, tape width, label height,
+ *                               and pixel lines [noLabelPreamble]
+ * @param Debug                  Emit diagnostic output to stderr [noDebug]
+ *                               (only if compiled with DEBUG set)
+ *
+ * Information about media type, resolution, mirror print, negative
+ * print, cut media, advance distance (feed) is extracted from the
+ * CUPS raster page headers given in the input stream.  The MediaType
+ * page header field can be either "roll" or "labels" for continuous
+ * tape or pre-cut labels, respectively.
+ *
+ * LabelPreamble should usually not be used for the PT series printers.
+ *
+ * <h2>Output</h2>
+ * Each invocation of this filter is one job, containing a number of
+ * pages, each page containing a number of lines, each line consisting
+ * of a number of pixel bytes.
+ *
+ * Output consists of job-related printer initialisation commands,
+ * followed by a number of pages, each page consisting of page-related
+ * commands, followed by raster line data.  Each page is followed by a
+ * finish page or (after the final page) finish job command.
+ *
+ * The following printer command language, printer, and tape
+ * information has been deduced from many sources, but is not official
+ * Brother documentation and may thus contain errors.  Please send any
+ * corrections based on actual experience with these printers to the
+ * maintainer.

+ * <h2>Printer model characteristics</h2>
+ * The following table lists for each model what kind of cutter it has
+ * (manual, auto, half cut), what kind of pixel data transfer mode it
+ * requires, its resolution, number of print head pixels, number of
+ * bytes of pixel data that must be transmitted per line (regardless
+ * of actual tape width!), and what kinds of tape it can take.
+ *
+ * For PC models, pixel data must be centered, so narrow tapes require
+ * padding raster data with zero bits on each side.  For QL models,
+ * labels are left-aligned, so pixel data must be right aligned, so
+ * narrow tapes require padding raster data with zero bits at the end.
+ *
+ * For PC-PT, only the central 24 pixels (= 3,4mm!) can be used for
+ * pixel-based graphics.  It might be possible to print several strips
+ * of 24 pixels side-by side by issuing CR and line-positioning
+ * commands.  That is currently not supported, let alone attempted,
+ * with this driver.

+ *   rightmost!
+ * - Bit image printing (BIP) using "ESC * ' #1 #2 ...data..."
+ *   probably only works for the PT-PC model.
+ * - QL Printer documentation might state that the print area is less
+ *   than 61mm, which is probably to ensure that printed pixels stay
+ *   within the tape even if it is not precisely positioned.  The
+ *   print head really IS 720 pixels.

- * @param filename The request file (if omitted, read from stdin)
- *
- * Available options (default values in [brackets]):
- *
- * @param PixelXfer=ULP|RLE|BIP  Use uncompressed line printing (ULP),
- *                               run-length encoding (RLE) or bit

- *                               (only if compiled with DEBUG set)
- *
- * Information about media type, resolution, mirror print, negative
- * print, cut media, advance distance (feed) is extracted from the
- * CUPS raster page headers given in the input stream.  The MediaType
- * page header field can be either "roll" or "labels" for continuous
- * tape or pre-cut labels, respectively.
- *
- * LabelPreamble should usually not be used for the PT series printers.
- *
- * <h2>Output</h2>
- * Each invocation of this filter is one job, containing a number of
- * pages, each page containing a number of lines, each line consisting
- * of a number of pixel bytes.
- *
- * Output consists of job-related printer initialisation commands,
- * followed by a number of pages, each page consisting of page-related
- * commands, followed by raster line data.  Each page is followed by a
- * finish page or (after the final page) finish job command.
- *
- * The following printer command language, printer, and tape
- * information has been deduced from many sources, but is not official
- * Brother documentation and may thus contain errors.  Please send any
- * corrections based on actual experience with these printers to the
- * maintainer.

- * <h2>Printer model characteristics</h2>
- * The following table lists for each model what kind of cutter it has
- * (manual, auto, half cut), what kind of pixel data transfer mode it
- * requires, its resolution, number of print head pixels, number of
- * bytes of pixel data that must be transmitted per line (regardless
- * of actual tape width!), and what kinds of tape it can take.
- *
- * For PC models, pixel data must be centered, so narrow tapes require
- * padding raster data with zero bits on each side.  For QL models,
- * labels are left-aligned, so pixel data must be right aligned, so
- * narrow tapes require padding raster data with zero bits at the end.
- *
- * For PC-PT, only the central 24 pixels (= 3,4mm!) can be used for
- * pixel-based graphics.  It might be possible to print several strips
- * of 24 pixels side-by side by issuing CR and line-positioning
- * commands.  That is currently not supported, let alone attempted,
- * with this driver.

- * - Pixels bytes sent are printed from right to left, with bit 7
- *   rightmost!
- * - Bit image printing (BIP) using "ESC * ' #1 #2 ...data..."
- *   probably only works for the PT-PC model.
- * - QL Printer documentation might state that the print area is less
- *   than 61mm, which is probably to ensure that printed pixels stay
- *   within the tape even if it is not precisely positioned.  The
- *   print head really IS 720 pixels.

+This patch fixes a number of issues with the ptouch-driver printer driver:
+
+  * Update the driver to use current CUPS APIs (not the older deprecated ones)
+    and fix some compile-time warnings
+  * Use the PPD API to get the value of the MediaType flag, which is used to
+    pass the "Roll-fed media" flag into the driver
+  * Correct the margins for QL-series P-Touch paper-label printers - these
+    have a fixed 3mm margin (see the command spec) while the PT-series
+    laminated plastic label printers have no appreciable margins.
+  * Correct the format of the "ESC i z" (Print Information) command to match
+    what is specified in the P-touch 500 raster command spec. Notably set the
+    "passed parameter valid" bits, and send valid values for die-cut labels
+    and continuous paper rolls.
+  * Send the "ESC i d" (Set Margin) command for QL series printers. This is
+    required by the command spec. The margin is set to 3mm for continuous
+    paper and zero for die-cut (see the command spec)
+  * Fix an issue with margins in the driver (disable blank-line padding). This
+    was partly responsible for the "excess paper feed" issue.
+  * Suppress the spurious "ESC i z" which was sent with incorrect contents at
+    the start of the job.
+  * Fix the Enable Cutter command.
+  * Send 350 bytes of NULL/no-op commands at the start of the job. This allows
+    the driver to recover the printer into a known state if communication was
+    interrupted mid-transfer. This is recommended in the command spec.
+  * Remove the "determined by page size" option from "Roll-fed media" as this
+    no longer works.
+  * Remove the "Advance Media" option, as this allowed users to configure the
+    driver to generate print control codes which are illegal per the Brother
+    documentation. This is now fixed at "Advance at end of job" (send a Form
+    Feed at the end of every page, except the last which has an Eject
+    command instead).
+  * Merge in the changes formerly provided by send-esc-i-A-for-QL-only.patch.
