由 ╄→гoц情女王★ 提交于 2019-12-21 02:54:15
问题 I want to code a litte utility that can print a page from a an URL, the URL would deliver a standard file (like a pdf or a jpg picture) and I just want to print this from within my cocoa app without showing any dialog, is that possible? I can't find anything about this in the docs except for a thing telling me to build a view with the file and then print this view but is this really necessary? Any help appreciated.

由 不羁岁月 提交于 2019-12-21 02:41:39
问题 I need to print the report from a Java desktop application to a dot-matrix printer (Epson LX-300 II). Report consists of text ang some graphics. Printer is connected via USB and I'm using CUPS to print. I'm printing using the Printable interface (pretty standard in Java). My problem: Text printing quality is very low on every printer resolution (60x60, 120x60, 120x72). It seems like there's no font hinting at all in some printer driver. Letters is looking very ugly. I can't use direct text

问题 I am using pandas and matplotlib to generate bar-graphs with lots of bars. I know how to cycle through a list of selected colors (How to give a pandas/matplotlib bar graph custom colors). The question is what colors to select so that my graph prints nicely on a paper (it is for a research paper). What I am most interested in is sufficient contrast between the columns and a selection of colors that looks pleasant. I would like to have multiple colors instead of gray-scale or single-hue

问题 This seems easy in Linux, but I'm trying to print the names of *.pdf files within a directory and its subdirectories to an output file. I have Perl installed on my Windows machine. What's a simple way to do this? 回答1: Not much different than Linux. dir *.pdf > fileyouwant.txt If you only want the filenames, you can do that with dir/b *.pdf > fileyouwant.txt If you also want subdirs, dir/s/b *.pdf > fileyouwant.txt If you aren't in that directory to start with dir/s/b C:\Path\*.pdf >
